We stayed at the place for 6 days as a group of 4 friends and all in all, it was great.
The kitchen was well supplied, we even had coffee pods and tea bags provided to us for a few days. The flat itself matched the pictures and was very clean.
We had two bigger issues that Joseph said he would look into asap: the bathroom door did not lock and we had an issue with the heating, so it was a little cold in the flat. We were out most of the day however so we made it work somehow. The windows also sometimes had a slight draft, so they don't seem to be completely isolating. That is probably only noticeable when the weather is cold out though.
Other than that everything was as expected and the great location so close to the nearest metro station made it easy for us to get around.
While we were there we wrote with May and Joseph about the issues we had and they both were very responsive and helpful.
