The apartment was alright, it might differ a bit from the images, as the apartment looks brighter and with more windows.
In general terms the stay was okay, we only had an issue with the luggage storage service they offered us. They claimed to be until midnight at the office where the luggage was, but when we needed to pick it up there was no one there, because of that we lost our train back home and had to buy 7 new train tickets. This is something to have in mind if you plan to use that service.
