Location was really good. It's right behind the blue mosque and you get to pass small shops and arasta bazaar along the way. There's a small distance of a steep uphill which may be a concern for small kids.
The unit is one the first floor and looks exactly in the photos. It's more like service apartment whereby light cleaning and towels were changed daily. The unit's kept clean and tidy at all times. Bathroom was not too small and is washed daily so you don't see any soap scum whatsoever. They've got quite good set of cutleries, pots and pans. Once, I accidentally left my iPhone in the unit prior to housekeeping and was quite worried it would be lost by the time we came back but to my much delight it was still there! Just beside the made up bed :)
The unit was comfortable for 3 adults and 1 small child. Not sure for 4 big adults tho. Maybe 2 petite adults on the small sofa.
Don't expect any fantastic views out of the window though. The building across is abandoned and an eyesore. That didn't bother us too much as the sheer curtains let the sunlight in without looking to the dilapidated building.
We didn't meet Saban though. Prior to arrival, Aycan did the correspondence and through out the stay, Zafer was there to accommodate us.
We recommend the airport transfer especially from the airport to the unit as there are so many taxi scams and it's best for first timers like us. We also took the boat cruise from the hotel which was great.
To sum up- it's a BnB with almost like hotel facilities- concierge at nearby sur hotel and daily housekeeping!
