Excellent appartment!
Very good location, walking distance to very different kinds of Istanbul: old historical Taksim and Galata in one direction, new and posh Nisantasi in the other direction.
The internet connection is ADSL, which is fine for everyday use, but the upload speed is only enough for voice calls. This is not critical for travel, but might be important if one intendes to work.
The appartment has a unique style, it's very pleasant and cozy, in principle could use some renovation, but more than adequate for the price.
We had a fantastic time, thank you so much Anne!
