We stay here few times already. The lounge was great, the food was generally very good, though occasionally some dishes, like beef or vegetables, were slightly overcooked /undercooked. We regularly shared feedback with the staff, and they were always responsive and took care of things. A big shout-out to the concierge, reception team, and the staff at the door, everyone was consistently friendly, welcoming, and helpful throughout our stay.

downside was the air-conditioning in the room. It was centrally controlled, so we couldn’t adjust the temperature ourselves. This was a bit disappointing, especially during the daytime when it sometimes got uncomfortably warm.

I liked the location, the hotel room and space, I liked spa pool, hamam and gym. I liked they provided me nespreso machine and daily capsules with water. Guest relation was helpful.

I didn't like the room view opposite other building and people so couldn't open curtains. I didn't like their key cards, I had to change them every exit as they didn't open the door, had to go back down every time. I didn't like that they promised me a nice high floor room with a view and got me to check in to a low floor, bad view at my night arrival with family so couldn't change after unpacking. They said they will do a nice setup for my wedding anniversary and we just got complimentary nuts and fruits on the table. The bed sheets and duvet weren't to a proper size and not properly fitted and tucked, I had to arrange them every night.

Clean, new hotel in the good location (few minutes from shopping mall, bus stop and metro station), I was reaching all places I needed in 30-40 minutes. Staff was polite and helpful. I had few problems and it was solved quickly. Didn’t have time to check out all facilities. Rooms are enough soundproof, was sleeping very well. The best thing in the end of long day - bath tab. The only thing - blankets are small and so thin, but I requested additional one , so it was fine . Temperature in the room didn’t go lower than 21, even AC was set on 19 and I wish could open window for fresh air (because of safety concerns it’s restricted). Requested late check out and it was managed so quickly, reception and supervisor are so helpful. I read a lot of reviews about other hotels where it’s cheaper and closer to touristic areas, but dirty, unsafe, staff is careless and they took some residents belongings. Don’t risk your safety and comfort, go for this hotel.

We stayed in the hotel for a week .. from the first day we arrived to Istanbul in the early morning and Mr. Yunis was so helpful and found me a room that I can check in in the morning ( not afternoon ) he was super nice .. the room service was okay .. the customer service ( phone ) were great they answer immediately and help you ( they don’t let you wait ) .. also the guys at the gate they help me with taxis and for any inquiry.. they always smile ! Friendly and so helpful .. the place is quit and near Nişantaşı it’s like 15 mins walk.. supermarket in front of the hotel .. namli ( best bakery ) also best to the supermarket .. everything was perfect in my stay

They don’t have scale for luggages

I loved that this hotel was safe .. the elevators can only be used by guests and staff .. this area is full of street beggars so safety is a priority .. additionally the staff are all very professional everything you ask for you receive in no time .. the hotel is very clean .. it is close to really nice cafes and restaurants ..

The place is favoured by many so it was very crowded and checking in was a hassle for me .. also I met few guests who faced problems due to paying in advance through the app, so I recommend you only pay when you checkin ..

I didn't tried the breakfast so I cannot really give my opinion, the room was great it was spacious and clean and the furniture is comfortable. The location of the hotel is 5 mins away from Jawaher Mall, and all services outside the hotel is near like restaurants and shops and supermarket is opposite of the hotel directly. Nisantasi is 12 mins walking distance, the location is great.

To be fare, I didn't have any negative statements of the stay in the hotel, just that the hotel price is little expensive.

The hotel is clean and pleasant. The location is excellent at the center of Şişli and only 250 m walking from Cevahir mall. Every thing is near the hotel and we like Namli cafe which is few steps from the hotel. The breakfast is very delicious. The staff were very helpful with pleasant attitude especially Mr EGE at the reception, he upgraded our room It was an awesome trip and I am looking forward to visiting the place again very soon

The location was convenient for me - that’s actually why I chose it in the first place. The room was extremely nice, and even though I made a last-minute request for two separate beds, they accommodated it without any issue. Breakfast was decent. I’d like to extend my heartfelt thanks to the hotel staff—they were all incredibly friendly and helpful, from the check-in team, staff that helps with luggaes,the breakfast crew - they were so friendly!
