I highly recommend this place for everyone! Yusuf and his staff try everything, to make the stay of their guests as comfortable and memorable as possible. Everyone is really easygoing, super friendly and welcoming and they won't only help you with tips on what you can discover in the city, there is almost always a cup of turkish coffee or tea waiting for you in the lobby.
The room is very stylish and spacious, as shown in the pictures. The acommodation is close to most of the tourist attractions, so you can easily walk there. I've had a great time and the next time I'll visit Istanbul that's definitely the place I'd like to stay in.
