The hole structure from D'Alex is very good. They are very professional and everything went in accordance to what had been planed and disused.
We were very happy with the service, as well as the apartment.
The apartment was very well equipped with a big kitchen and two rooms in which 6 people would easily fit. The apartment is in the basement, so it's a bit cooler, which was an advantage in the hot summer days. The only small issue was that the mattress on one of the beds was quite used and therefore not so comfortable anymore.
Other then that, everything was great.
I would strongly recommend it :)
