We have never given an unpleasant review, but we were let down a fair bit in this particular case.
The pros would include that the apartment is located in a great location within the City, and everything you might need is very close by. A city map was given, the hostess was very polite and was available to answer any questions.
The cons:
When we arrived, we were asked to wait a little bit outside the door (presumably so host could finish the seemingly rushed clean-up job from the last residents). Later on, after we ended up making some food, we realized that there was no dish soap and no drying towel to wash our dishes. We were unable to open our wine bottle because there was also no corkscrew.
The description fails to mention a pretty low ceiling in the bedroom and bathroom, so if you are taller than 5 feet 5 inches, you have to crouch while standing up and while showering. It is manageable though, for a short period of time. The description also says there is a king size bed. It is more like a twin size bed, and the mattress is not very comfortable (pretty hard). upon arrival, we were told we have to pay 2 euros per person per day for a city tax, so we ended up having to leave 12 euros on the table. This would have been fine had we been notified prior (should be in the description).
2 out of 3 nights we were there it rained very hard. Water began to leak through the roof into the apartment in 3 different locations, which woke us up at 2 AM and kept us awake for awhile as we tried to contain the leaking. Because we had to use the two bathing towels provided to soak up the water and to dry dishes, we were unable to shower. We could have phoned and asked for supplies, but we were so busy during the day with booked excursions we didn't have time to deal with all of it.
