All in all it was a very good stay. Nice place, very convinient, very stylish, had the facilities I needed for cooking. When I had a problem they imidiately answered and sent a guy to help, and the communication was excellent.
The only three bad things I can say are:
1. It's pretty dark - there is only one window, and it's right on the street so during the light hours I usually didn't open it at all and the entire apartment was in the dark. It's a pretty side street so there weren't too many people but still.
2. It wasn't anyone's fault but there were constructions right in front of the apartment while I stayed there. It woke me up every morning and there were some people outside all day long (brings me back to the window problem). And there was always some noise from the neighbors from the bathroom window (which did not bring any light in because it was interior).
3. There were missing some essential facilities for cooking such as salt and oil.. But I managed.
I had a really good time in the apartment and I will recommend, but I feel like these are things that you should know before you book it.
