A perfect place to stay in Istanbul. The apartment is very well located (half way between Taksim and Tünel, close to Galantasaray Square), and offers spacious accommodation for up to five people (in three bedrooms) or somewhat less spacious for up to eight (including the living room). Everything is brand new and spotlessly clean. The apartment has everything one could wish for as a tourist for a short or even mid-length stay.
Communication with Garen was easy and helpful, on arriving, he met us in the vicinity of the place and led us there. In the immediate vicinity there were several nice little grocery stores and even a decent little restaurant. And try the chicken roaster one block up the street! Simple and yummy. Same goes for the assorted roasted nuts from the liquor store across the street. Yummy again.
When I return to Istanbul, I will certainly look up Garen to see whether his place will be available!
