Great place! I stayed at Ali's apartment for a full week and enjoyed it very much. The communication with Ali was super smooth. The apartment has such a warm atmosphere and it's at an excellent location in the center of Beyoglu on easy walking distance to Taksim square or the Galata bridge. It's also easy to reach from the new Istanbul airport, in 45 minutes by bus plus a 20 minutes walk. Because there's a popular restaurant below the appartment there's quite a bit of lively sound till late at night so perhaps, if you're sound sensitive, you should consider earplugs for sleeping. And if you open the windows for some fresh air in the evening, beware of hungry muskito's ;p All in all I would definitely return here and I'm a big fan of your postcard collection Ali! ;D
