It was a really nice place, we had very good communication with Jens. No problems with check-in and check-out. We didn't have the best weather outside but in our room it was really warm - a big advantage of this offer ;)
When we were coming to Brussels it was snowing, so Jens wrote us that we may have some problems with public transport in the city and suggested what will be the best way to get to the flat. Thanks to this suggestion everything was fine, we really appreciate it ;)
