I can recommend the flat and the area. Still, it was hard to communicate with the host, the concierge didn't want to let us in because we were not told the apt. number so we had to wait. The response time Was quite long as well, furthermore we had some issues because we had two friends that had to sleep at ours (to be fair that was our mistake, not the hosts) but the requested price afterwards for those friends was far to high and not fair. Furthermore it was extremely complicated to communicate in an appropriate, neutral and informative way.
To sum up: the flat is nice and I can recommend it but I wouldn't go there again...
