While the owner gave pretty clear directions to the apartment building itself, it was still confusing trying to figure out which flat was the rental. We had to ask for help. Directions for opening the lock box were clear, but then the actual door knob came apart while trying to enter the apartment. Only the bolt lock worked. The stairwell leading to the room was disturbingly dirty, and some people were openly doing drugs in the stairwell both nights of our stay.
One bathroom only had lukewarm water for showers, so we all had to take turns with the other one.
Although the location in relation to Old Town was great and the interior was perfectly fine, I would not use this rental again nor recommend it to others.
