This is actually a small hotel one street down from Istiklal str.(the main street around Taksim area full of shops and restaurants and movie theaters). The place exceeded our expectations as the staff was very kind, always willing to help out and caring towards their guests.
We were given actually a family room of three despite us being two and though on the last day I mislocated the keycard, the staff was too kind not to make an issue out of it (it was inside my phone case all along, go figure).
My husband had to leave earlier and for us both, they arranged airport transfer ( 200 TL, $30) which was an okay rate though with a cab you might get it cheaper. The cabs are in Istanbul is an issue though thus, I recommend the airport transfer arranged by the hotel.
Overall, it was great. The space looks just like the pictures, a bit small but that's okay given the location of the hotel. If you are looking for an easy place to stay at, close to all fun things in Beyoglu area and Karakoy area, we definitely recommend this hotel. It will be worth every penny spent!
