Had to book a last minute room since my flights were changed to arrive to Istanbul a day early. They responded to my booking request within minutes.
Haus was so good that I tried to cancel my original hotel bookings and extend my stay with them (but it was too late). Great location, great interior, friendly staff, and impeccably clean. On a quiet corner but still a stone throw from the bustling streets of Taksim and Beyoğlu.
I will certainly be back, and will recommend Haus to everyone I know!
