I loved this place the moment I walked in: a cozy vibe and perfect for what I needed. I had been staying in a hotel in the Old Town but it was rather damp and chilly (January). I had no such problems here - the apartment was very comfortable, water was hot and the shower powerful.
Very quiet at night (barring the occassional mad moped driver zooming down the alley, but that's a hazard throughout the Old Town).
There are extensive cooking facilities, including an oven, which I didn't use during this short stay but that would be very useful for a longer stay.
I stayed only three nights but I would certainly go back and recommend it to others.
