We enjoyed our stay at Berk's place. It is well located (30 mins by foot to Moda district, several shops and markets around), a nice building. The apartment is quite, no noises. Everything is in place: kitchen is equipped, detergents in the bathroom, TV (we didn't use though, but it's there). A table where you can work or/and eat. During our stay an A/C was installed. The place is very clean, too.
Even though we didn't speak any Turkish, we got by with the help of Google translator. Berk is a friendly and welcoming host. We are happy to leave a positive review:)
