We stayed at Berra’s apartment for a week. She was friendly and hospitable, welcomed us herself and brought us towels that we requested later on. The flat was clean and as the pictures show you. Regarding the disadvantages, it is quite dark there as the flat is located on the ground floor with windows overlooking the wall of the nearest building, but I guess for Istanbul this is a typical matter. Our neighbours were quite noisy at night, and you hear every sound, every text message being sent in another flat, etc.
The location is very convenient, everything is on your doorstep. The internet was fast, we worked using video calls w/o problems. Thank you Berra for your attentiveness and politeness!
