The house is very well located. My colleague stayed for 5 weeks in the apartment and liked the neighbourhood a lot. The apartment itself had all the things you would expect from an apartment, including dishwasher, washing machine and dryer. The patio is cosy but small and there is hardly direct sunlight in the apartment.
It is silent since it's located at the back of the building, so no noise from the street (trams/cars) that are passing.
Unfortunately my colleague lost one of the 2 keys (due to a weak key-ring) and the host is requesting €249 for the lost key. This issue is still under investigation at airbnb, hopefully they'll be able to find a proper solution.
