We believe this is the best apartment we stayed in during our five-city trip in Italy. The building appeared small and untrustworthy from the outside, but the unit room is great. They also have larger (deluxe?) rooms. It is an old building that has been renovated in a modern style and equipped with modern amenities (a good kitchen, a washing machine, a microwave, and a coffeemaker). They even gave us a complimentary bottle of wine as a welcome gift. They provided us with not only kitchen utensils but also oil, salt, and other basic cooking ingredients. The shops and restaurants are located directly to the right or left of the apartment. The nearest grocery store (CONAD) is only 100 meters away. Near the apartment, there is a market that sells a variety of local foods. It is also close to the Arno River. One more thing: they waited for us! When our taxi pulled up in front of the apartment, Herman (or German? the staff) greeted us and promptly assisted us with our luggage. We were immediately made to feel at home. Silvia is also cooperative and communicative. Thanks!

Nothing.

High ceiling art apartment with modern interiors, squeaky clean bathrooms and great location.

Apartment lighting went off every time any family member opened the door. Imagine lights and AC going out on a family member in bathroom if another family member stepped out. This is what happened with us. We had to insist on getting the keys reprogrammed so that this problem disappeared. Seems like an energy saving initiative gone too far and wrong. Except for this initial hurdle, it was one of the most memorable stays for all of us:

Great location, very clean, and has all the facilities. Modern and eco-friendly

It has no parking and all the nearby parking are either busy or very difficult to access for 7 seater car. The bathroom in the one bedroom apartment has no real door, just a glass partition with limited privacy

Well furnished, well equipped. Comfortable size for family with 4 kids who liked how it looked. Super popular sandwich place just a couple of doors away so you can be first in line for when it opens at around 10am. Restaurants and small grocers and a supermarket nearby. Close to Uffizi Gallery (great for morning first in line visits and avoid queueing) and the Galileo museum. Brilliant.

Great apartment but it'll be a long walk from the train station so if you are going to be taking the train out for day trips you'll be clocking quite a few steps.

The apartment was amazing! Seriously! It was so beautiful! We were not expecting it to be so big, spacious, clean and decorated very classy with its art and glass. We walked in and we all said, “WOW”!! The location couldn’t have been any better! It is located in a famous sandwich street with lots of restaurants, sandwich shops, cafes, gelato, and souvenir shops. A few steps down the street you have a grocery store, museums, bars, etc. The location was perfect! Hotel staff were amazing! They were so helpful with our luggage and any questions we had. This apartment was very clean! There are many lights in the rooms. There was a washing machine with a dryer cycle ( we loved that it dried out clothes too), refrigerator, stove, dishwasher, and toaster oven. Not to mention an espresso machine! Not only that, when we got to the room they had a bottle of wine on the kitchen counter as a welcoming gift! There is a small elevator which worked perfect for for my daughter and I and my husband and son enjoyed taking the stairs. I can’t say enough about this place! We have been on a 3 1/2 week vacation and 7 different hotels/apartments and Karios is by far our favorite! We didn’t want to leave. If you stay here, there is a coffee cafe just a few doors down with a window to order in the morning. They had great croissants, cappuccinos, espresso, and coffee. Croissants either plan or with many options, ex: with lemon custard, raspberry custard, ham and cheese, etc.. You just can’t go wrong here! Beyond perfect!

Nothing!

The property is a great location for walking to Florence sites. Beautiful finishes and furnishings. Excellent staff offering top notch service. We enjoyed our visit very much. 4 adults with two separate bedrooms, each with a full bath.

Hard to operate the W/D. An instruction page would be really helpful.

Not considering anything else except location, this apartment deserves the best possible star rating. We loved being able to walk to so many great locations that were right from the steps of this apartment. On top of that, the unit was very recently renovated, with very thoughtful design elements that fit with the old city, but with modern finishes. There were three of us on this trip, which included 16-year-old who slept on the pull out couch. It was slightly cramped when the pullout couch was pulled out, but I can’t complain too much about that, as that is the nature of pull out beds. We also liked how the facility was accessible through key cards, as opposed to having to carry around keys.

There’s not much to really criticize about this unit, except for perhaps the size if you have more than two people. However, I only mention this minor issue because I really have nothing negative to say about the apartment.

Everything! We were glad we took a cab from the train station, as the streets of Florence are VERY crowded and hot, but the apartment is centrally located to literally everything once you drop the luggage off (we walked 10-15 minutes to about everything, but we loved it and expected to walk). The property is clean, the staff wonderful, beds comfortable and while we did not cook, we definitely used fridge for leftovers and some fruit from the local market...we also took advantage of the washer/dryer in the unit, as we had already been in Europe for 8 days on arrival. The air conditioning worked great and there is a grocery market super close. We felt it was worth the money we spent for our family!

Really can't think of anything.

This hotel was truly a find. It is an apartment hotel, meaning that the units are apartments not regular hotel rooms, and located at the end of a bustling pedestrian only district near the Arno river between the Ponte Vecchio and the Ponte alle Grazzie. It's a ten minute walk to the Uffizi Gallery, great restaurants, shopping, and a 15 minute walk to the Duomo and Gallery Academia (where the David statue lives.) Literally the best gellato I have ever eaten is located across the street from the Kairos at Gellateria de Neri, and the pizza place adjacent to the building (Berbere) has some of the best pizza we had in all of Tuscany. And another bonus, one of Florence's star restaurants, La Buchette, is on the next block. But, back to the property itself... the one-bedroom unit we stayed in was pretty much brand new, beautifully decorated, and nicely appointed with kitchen, fridge, utentsils, comfortable beds, a sofa bed and a WASHING MACHINE! After ten days traveling that washer-dryer was a godsend. There was a welcome bottle of wine, a very nice touch. The staff was responsive and housekeeping was readily available at the guests' choice. We always work while traveling and the wifi was very good in the rooms. Blackout curtains kept out the street lights and the air conditioning kept the temperature chilly on some very warm nights. The only slight annoyance was that the sofa bed was a bit smelly from a previous guest spilling some kind of food substance on it, but we asked that it be cleaned and housekeeping took care of that right away. We will definitely stay here again.

No complaints. Great experience.

Best rental we had in Italy! We were in Rome, Venice, and Florence and the Kairos apartments were by far the best rental we had! It’s clean, beautiful, modern, comfortable and within walking distance to all the sights! We loved having the 2 bedroom apartment with all the amenities of a hotel. It was nice having a washer and dryer so we can do our laundry. We also really appreciate having access to the luggage storage cabinets in the lobby once we checked out so we had somewhere to store our luggage since we had a few hours to spend in the city before our train left. They provided us a code to the locked doors so we can get back to the lobby to get our luggage and use the restroom before heading to the train station. Sylvie and her team at the apartments were so welcoming, genuine, and kind. We will definitely stay here again if we get a chance to go back to Florence!!

Nothing at all!
