Very clean and very well equipped apartment, except for a very stinky stain on the sofa. The sofa got a clean during our stay - demanded by us - and proffessionally handled by our host. The result was ok, but - the smell was still there. The rest of the apartment was spotless though and we really appreciated the little extras like schampoo and dishwasher tablets.
Noisy neighbors above (shoes on hard wood floors, and closet doors being closed and opened) at very odd hours, several nights in a row is what really brings the value down for this apartment. Earplugs was a must in the master bedroom. We understand that this is out of our host's control, however still a pretty seroius problem for the visitor.
