We really loved the apartment, the surroundings and conditions. If there was absolutely no issue with the apartment I would rate the maximum score as it was lovely, well located and it was super clean. The phone service was good as well, but a bit late on action while solving problems.
Sadly, there were two issues with our stay:
1. Water heater: one of the nights the heater stopped working (error F1) and the house got cold pretty quickly. We reached customer support and we were around 3 hours on the telephone with 3 different people. At the end we were the ones fixing the issue, after instructions from the support. We couldn't take baths that night due to water temperature.
2. TV: Was not working when we arrived and the host suggested to fix it while we weren't on the apartment, which made us uncomfortable.
We've approached the host later and no compensation was provided on this issue, so before booking review with host the heater condition. It would be 5/5 if this hasn't happened.
