Great base for a short stay in Madrid. Easy walking distance to most sights and main shopping area. Nice size for 2. Great to be able to do washing. Well set up in kitchen. Didn't cook but nice microwave and good facilities in kitchen if you wanted to. Nice and quiet and warm. Small bathroom but that was expected.

Getting in make sure you read instructions in full. Need to download app. Wifi available to do that. Nearly got locked out on last day. Check out was later but could not get in on last morning when one of us went to supermarket. Code wouldn't work. Dark in the foyer.

The price was excellent for such as an apartment.

The AC was not good.

Localization, cleanliness and comfortable beds.

The key code was handled through a link, in which two buttons would open either the front door or the apartment door. If something failed you could also use a pin code. The place is in an underground, with a few small windows which let some natural light come in. It might not be for everyone, but taking into account the fact that everything was clean and worked perfectly fine (kitchen, washer and dishwasher, coffee maker, etc), the price, location and how quiet it was during the night, we can't complain at all. We will return.

Some of the furniture was a bit worn down, and one must be careful when going down the stairs, which might not be for everyone.

Fantastic location. Great apartment overall. Comfortable bed. Quiet. Good value

The hot water broke down on my last day and given that there is nobody at the building who works with Slow Suites (and no easy way to contact anyone either, which I could find at that time), first I wasted about 30 minutes trying to fix it and then I gave up given there was more time left and I had to take an extremely cold shower which was awful.

Perfect location. Very close to everything in Madrid centre. Fancy and innovative check-in/out process. Electronic access to the apartment works perfectly. We found everything needed for our stay. Very clean and exactly as shown in the pictures.

Bed in the first room could be bigger. (I must confess this could be challenging to organise due to room size. However, this is not a deal breaker, and I would highly recommend this apparment for your stay in Madrid.

Location, size and comfy beds. It was really clean except the tobacco smell :( has all the amenities to make a simple meal, powerful nice shower, and nice system with the door, easy to open. Lots of gluten free and vegan resturants and bars around. Very lively and safe area.

Smell of tobacco in the entire appartment was very strong for me...its not their fault that people break the rules and the cleaning stuff told us they are trying to get rid of the smell but it was there... it also doesn't take much sun but I knew it as its an internal flat.

In City centre. Contactless check-in . Provided everything which was described. 20m away from supermarket. Definitely recommended

Being our room in the basement. The whole flat was kind of chilling cold. But no complaints as we went in summer.

Location superb, all clean, good size, comfy beds.

We missed 2 big towels because the big towels were only put on the beds, but we were with more people and also slept on the sleeping couches. They did not take this into consideration. Water in one of the bathrooms did not go down so well.

Excellent location and neighborhood! Comfortable apartments. Will choose next time.

Very complicated and long pre-registration process, especially if you are with a large group.
