Daniel was a communicative host who tried to help us sort a host of issues with his studio. However, there were quite a lot of issues.
First, the studio was not very clean, there were layers of dust in many places (bedroom and kitchen), the sheets were most likely not changed because there was some hair in them, there was a mirror simply lying on the floor, things just weren't proper. The only place that was decently clean was the washroom.
Second, I got locked in the bathroom because the door handle was spinning without actually opening the door. I informed Daniel about this issue and hopefully it is repaired in due time before anyone can get locked for a long time.
Third, the building is old and some things may go wrong. The bathroom lock was not the only issue of the sort, I also stayed the night without heating during winter time. Luckily Daniel provided me with an electric heater, which improved the situation.
All in all, you get what you pay for.
