The apartment was easy to find and highly accessible to trams and trains. High-tech check in procedure without having to meet the hosts which is both a plus and minus as the human touch was a bit lacking. Generally, apartment was ok and the reason for the non-5 star rating was the loss of heated water on our 2nd night. We had to go to bed without a hot shower and it was not fixed the next morning when we checked out(apparently the whole building had issue with the water heater) Communication response was slow when I reported that issue. It appears that nobody monitors messages after 6pm and that was when we reported the problem. I tried phone messaging too and no response. I only got a response 8-10hours later
