ideal location: quiet street in a good area and 3 minutes to the metro. room is large, everything is modern, beautiful. very comfortable mattress and pillows. It’s great that there are blackout blinds on the remote control.

Several times a day Wi-Fi might not work (not for long, but still uncomfortable). you can only connect 3 devices... the soundproofing of the room is bad (like everywhere else in Istanbul), but I was lucky with the neighbors (at first they were quiet, and then no one)

The bed was too soft .

A brand new hotel, super clean. Amazing bed, enough facilities, tidy bathroom, friendly staff... I would say the cleanest room you may find now in Istanbul. There is nothing negative about the room itself. Ten out of 10. The first time I saw the room was the same as the pictures shown. It's located in a real local area surrounded by numerous clothes and other shops. Accordingly, you may find it too busy and not a relaxing touristic place. However, I only cared about the cleaness as well as the proximity to the metro station. It's in 1-2 min walking distance to metro M2 line. So, you can get away from the crowd and enjoy the rest of your day outside ;)

It’s my 4th stay at Hallmark and it has been a great experience so far! The location is fantastic - in the very center of Nişantaşı, close to everything. At the same time the street itself is very quiet so you can escape the hustle and bustle of the city. The room is clean and spacious, bed and cushions are comfortable. Bathroom is spacious and feels fresh, includes all the toiletries you need (you get here more than most hotels offer). The room has been cleaned properly. Hotel staff are very helpful - special thanks to mr Alihan for all help! I’m looking forward to staying here again during my next trip.

Amazing hotel best service ❤️highly recommend

The property was clean and comfortable in a great location right next to the train station, allowing us to easily access all the prime locations in Istanbul within minutes. The staff provided excellent service whenever required and allowed us to check-in early and provided us with a free upgrade because it was our honeymoon.

There was a fuse during one of the days and we woke up from the heat because the air conditioning stopped working and took some time to fix. A maintenance worker was called out to resolve the issue though.

First of all staff is unbelievable helpful and kind. They have tried to do everything to make our stay more than confortable (even they made efforts and gave us a room quite earlier then check-in hours). Hotel is spotlesly clean, very comfort, all needed amenities for a great stay, even a Nespresso coffe machine! Speaking about neighborhood, you can come and go whenever you want, it's super safe and lightly everywhere on the streets.

Liked everything, didn't liked - NOTHING

I’m very glad I chose to stay at this hotel! It was incredibly clean and well-maintained, which I truly appreciated. I felt so comfortable in the whole area, and the hotel’s location is perfect, close to everything you might need. The staff were absolutely fantastic – friendly, helpful, and always with a smile. Thank you all for making my stay so pleasant! I will definitely book this hotel again on my next trip to Istanbul. Best regards, Mariam

Location near shopping area of Osmanbey

Cannot connect to wifi

The room was very clean and the bed very comfy. I appreciated the fruit and chocolate welcome tray that was waiting for us in the room. The room was quiet. Amazing value for the price range.

The reception area is very small, fills up pretty quick, so if you are waiting for a cab you might not find a place to sit. The area where the hotel is located is an area for wholesale shops, but yet a few feet away from the main street.
