We really enjoyed our stay at Volkan's place! The location was great - it's located off one of the main tourist areas it's just 10 minutes walk to 2 metro stations. The apartment was very light and also very warm when we needed it (we stayed in February). Volkan very kindly let us check-in early and check out late because of our onward travel times. We thought it was excellent value for money and had plenty of space for two people.
A few things to take into account is that the apartment is basic (which the price reflects) and could do with some updating. There were 5 flights of steep stairs to walk up, which wouldn't suit everyone. And there was a drain smell from the bathroom, but keeping the door closed prevented this from spreading to the rest of the apartment.
Having said that, none of these things really bothered us and we would stay here again! Thank you!
