The apartment was really nice and in the city centre. During our check-in they had some issue with the cleaners (the apartment had not been cleaned when we arrived) but they resolved the problem in short time.
PRO: nice apartment; quite neighborgh; nice location in the city centre.
CONS: the big black table in the living room was broken (be careful!!!); inconvenient time for check in.
I would like to point out that they provide you a future discount in their apartments if you give the 5 stars score in the review. I do not think this is fair, and I believe this causes bias in the final apartment score.
