Riza's place was a great choice for me. It might not be so clear from the pictures, but there is a really nice bit of space here, with separate living and eating areas. From the dining area you can see down over in the distance to the Bosphorus, where the ships pass through the day. The internet was really great there, I could reliably do work by Wifi. Location is nice and easy to get into Karakoy, or over to Galata, Taksim or to take the ferry or tram to other areas. It was perfect in this regard for me. When my trip was cut short due to flight cancellations, Riza refunded the weeks I couldn't be there for, which he didn't have to do. In addition place was quiet, secure and there are some good places to eat on the doorstep.
