A friend and I stayed at Isik's flat for 4 nights on a short visit to Istanbul. The flat had everything we needed and more, including a double bed and a comfortable couch turned bed. Darts board provided entertainment when it rained heavily one night! Kitchen amenities all looked good although we didn't use them. Bathroom was clean and sufficient and although the shower was on the blink during most of the stay, Isik made every effort to fix it. Located near Taksim square meant restaurants, bar and nightclubs were all easily walkable. Most of the tourist sites are close with public transport (Isik usefully provided Istanbul's version of an Oyster card too on arrival) but we walked mostly which was no problem (for guys in 20s) and nice to see the streets. Overall, a lovely experience and would definitely recommend.
