Ali is a friendly and caring host! The apartment is close to Taxim square where you can find all kind of transport: metro to the old city center, bus to/from Istanbul airport, funicular to tram/ferry/bus station (don't forget to buy Istanbul card, since Uber isn't effective there). It is also close to famous Istiklal street.
Ali was very communicative, kind, and helped us to find the place where we left our bags while waiting our late flight.
Thank you, Ali!
