We stayed for a month in Istanbul, the apartment was a great base to explore, very convenient, within walking distance to Galata Tower, İstiklal Caddesi, lots of restaurants in Karaköy, the new development at Galataport, and the tram and subway. Lots of great options for food!
The apartment was nicely set out with all the facilities we needed and comfortable furniture (inc. a large TV and a good-sized desk for work) and our host was extremely helpful at check in and during our stay, and the one time we had a problem with the power he came over immediately to help. The internet was consistently fast, which made catching up on work easier.
While we were staying (March 2022) there was some construction work in the apartment above, but it was only because I was sick for a week and stayed home that we noticed, it was during the middle of the day and stopped by afternoon / evening.
