We thoroughly enjoyed our stay at Muge's flat.
The taxi drivers had no trouble locating her apartment. We used Istanbul's local taxi app called BiTaksi and it was a simple and great service.
Upon arrival, Muge's housekeeper met us and gave us the keys. Her flat is in a quiet residential area, within a 5 min walk to a metro station and a 5 min walk to Taksim square, which was great that we could go shopping and eat a late dinner and be close to home. Her neighbors are friendly and quiet. We felt safe walking home late every night. There are also plenty of local markets nearby if you need to pick up some water and snacks.
The air conditioning worked well and there is a nice table and cute outdoor patio. There also was a washing machine and drying rack provided. The iron is located in the cabinet underneath the TV.
We didn't use the kitchen much but it was functional and room for several people at the dinner table.
The master bedroom is very nice, and the other room fits a single bed.
The bathroom also had a nice sized shower and her wifi worked well.
All in all, a very good experience and very conveniently located.
