Oveall, it was a great stay, both Eddie and housekeeper Ameen were super-nice, always ready to help, suggest something or just chit-chat.
Would definitely return back again!
The location is great. In just 5 minutes, you can reach İstiklal, cafeterias (you should definitely try a Turkish breakfast served there), shops/mini-markets (like Sok, Carrefour), pizzeria, etc etc. If you're looking for a craft beer, you can find some in Babel down the street.
Public trasport is not far, in just 10-15 minutes you can reach a transport stop.
Quite many sightseeings are around to visit, too.
Didn't have any troubles with the flat either. The stairs on the 5th floor are quite heavy, though, but the view was totally worth it! Wi-fi was acceptable, enough to watch online movie. But if you need to make some voice/video calls, it may not be enough. Local cellphone card worked better. The washing machine (with dryer function) is located in the basement, and free in the evenings.
