We stayed in Bahar's place for the entire month whilst working remotely, so our perception has a bit different angle from other tourists.
What we liked:
1. Bahar is an incredible host, she was very helpful throughout all our stay in the apartment. She recommended a taxi company to drive us from the airport, helped to rent a desktop monitor for work, provided a lot of recommendations on what to visit, and a lot more. Bahar was easy to reach, always provided rather quick response and help when needed. We felt in good hands. Many thanks to her for such support!
2. internet connection was very good; 3 of us working remotely didn't have any problems
3. views from living room and one of the bedrooms to Bosphorus were very nice; we loved them
4. location was very convenient, in the tourist area, close to tourist attractions, about 5 in away from the tram and metro; there is also a grocery shop just in the opposite building, and quite a few restaurants around.
5. apartment is rather spacious, two of the bedrooms are spacious too;
6. building has an elevator, which was very convenient
What we didn't really like:
1. as a side effect of location in the heart of tourist area, it is quite noisy on the streets around. Two of the bedrooms face Galata tower: amazing view!, but rather touristic street with noises up to early morning. For a couple of days it is ok, but for our stay of 1 month it was quite a challenge to get proper sleep.
2. two of the bedrooms are spacious and isolated, but 1 bedroom is small and is walkthrough, so no privacy there really.
3. furniture in the flat is pretty worn out
4. rooms are separated by glass walls, and sound proofing is not really a thing there
5. flat can technically accommodate 6 people, but the dining area in the kitchen can fit only 4, and bathroom is pretty small: we barely had enough space to put there stuff for only 3 of us.
