We had our breakfast in the Green House. Breakfast was good and has many options. The place is also very nice and relaxing. Great way to start the day with good food and comfortable place!

I can't think of anything.

We came to celebrate our wedding anniversary and Hilton did everything possible to make it special. The room was luxurious, staff were very friendly and helpful (the shuttle around the property was heaven sent during the rain!), and the Turkish breakfast in the Green House Garden Restaurant was both extensive and delicious. Easily the best location in Sultanahmet for seeing the main tourist sites.

Bring earplugs for an uninterrupted night's sleep. The proximity to the Hagia Sophia and the Blue Mosque means you will hear the call to prayer in the early morning hours.

Beautiful property perfectly located in the heart of Sultanahmet, just steps away from the main attractions. The suite was large, spacious, and tastefully decorated, offering a safe and comfortable stay. The staff were eager to help, and the reception team provided golf cart assistance to/from taxis etc. which was especially nice when arriving back at midnight from a tour in Cappodochia. The person who made the beds arranged the towels in different shapes (alligators, swans etc.) each day. Very creative. An oasis of calm amidst the bustling tourist area. We’ve stayed at many other hotels in the area over the years and there were usually problems. This one was run smoothly. Would stay there again.

Istanbul saw snowfall during our visit, making our exploration of Sultanahmet cold yet wonderfully enchanting. This historic neighborhood is home to the magnificent Ottoman-era Blue Mosque, with its elegant minarets, and the renowned Hagia Sophia, adorned with stunning mosaics. Our hotel was perfectly located for exploring these iconic landmarks, with the Grand Bazaar just a 10-15 minute walk away. The staff were delightful—polite, welcoming, and incredibly helpful—making our stay truly memorable. The concierge was fantastic, expertly arranging our Old City Tour. We were delighted to have chosen this hotel for our first visit to Istanbul.

Nothing.

Our stay at the Hagia Sofia Mansions, Curio Collection by Hilton, was nothing short of fantastic—truly a 5-star experience from start to finish. The location is unbeatable, right in the heart of the historic district. It’s just a two-minute walk (if that) to both the Blue Mosque and the Hagia Sophia, and all of our tours conveniently met at the Hippodrome, just a few minutes away. The hotel itself is a collection of beautifully restored mansions, and we had the pleasure of staying in the main one, the Green House. As a honeymoon treat, we were upgraded to a spacious suite free of charge, which was a wonderful surprise! The room was beautifully designed, and the bed was incredibly comfortable—one of the best we’ve experienced while traveling. From the moment we walked in, we were captivated by the vibrant decor and the incredible fragrance of their signature atomizer (if I could have bought one for my home, I would have!). The entire property was impeccably clean, and the staff was warm, welcoming, and always ready with helpful recommendations. We highly recommend opting for the breakfast—it was an impressive spread and the perfect way to start each day. If you’re looking for a luxurious and centrally located stay in Istanbul’s Old Town, this is the place. We would absolutely stay here again!

Nothing, everything was perfect!

The hotels location affords you a wonderful tourist free night time, and you have the historic sites to yourself. They really do all disappear! The spa was set in an amazing space. The bedrooms were excellent and most importantly quiet despite the early morning calls to prayer. The bathrooms are a delight and beds very comfortable for sleeping in and more! You can walk to most of the main tourist attraction easily and there are numerous restaurants and good coffee shops around the area.

The restaurants were a little soulless.

The staffs were great, Nozima,Yigitcan, Mr. Aren, and etc. The location is the best! We feel so comfortable to come back to our room -- it's like our home in Istanbul. When the tourist crowd is gone at night we feel living in the old palace, or at least in the neighborhood of Sultan's house. Very special and precious experience that we will cherish for a long time.

The hotel restaurant (we tried the breakfast at Green House) is kind of over priced. When I booked the room at booking.com it indicated I can get a breakfast for one person at 12 euro but when I asked the waiter he said that price is impossible.

The location, the hotel facilities and the friendly staff. The hotel was within 5 mins walk to the Blue Mosque, Hagia Sofia Mosque and the Palace. That was so convenient for us in terms of managing our time. The hotel was beautiful. Its facilities were very good and so much comfort. The staff was very friendly and always did a good job in taking care of our needs. Always made sure we were safe. On the day we checked in, the concierge made sure to show us where all the places were that we wanted to visit, and later made sure to pick us up from where we had gone for dinner. We really appreciate how well we were taken care of by the staff.

Great base to explore Istanbul from, being just round the corner from the main sites, it made it easy to beat the crowds in the morning, and enjoy the area without tourists in the evening. The courtyard near reception is a lovely refuge for a break during the day/in the evening. Both buffet and order-from-menu breakfasts were great, and we also enjoyed dinner at the greenhouse restaurant one night. I booked the cistern spa for one evening and it was fantastic and even healed my foot that I had twisted on the cobbles during the day! Wonderful staff - particularly enjoyed being sent off with water when leaving the hotel. Would definitely love to stay again when back in Istanbul.

While we loved the room itself and the view of the mosque/parrots in the tree/street, the trams running every 2 minutes woke us up very early, on the positive side, this got us up and exploring much earlier that we would have done otherwise.

If you are staying in Sultan Ahmet area, nothing can beat this location and the quality of accommodation. The rooms were beautifully decorated and it felt like we were living in a palace. Front desk was understaffed and there were always queues.

Understaffed especially for breakfast areas and the breakfast was also very ordinary with no personal touch on the buffet breakfast area whereas the traditional Turkish breakfast was better but the quality of the service was 2 out of 10. The lights were too confusing to operate. We could not get the hang of operating the lights in 2 days of our stay.
