The good: proactive, responsive host (+ 25 euros - see below)
The bad:
It seems a bit shady to me to ask for 25 euros to do an early checkin/checkout (the normal hours are 16:00/11:00) But that's fine, since I arrived at ~ 17:00
The building has an intercom but they told me to just push the door harder to get in. I don't think that's how things should work, but I also saw others do that so maybe?
The room was not cleaned from the previous guests. I complained to the host and they immediately sent someone to clean the place. They also sent back 25 euros which is nice. The place was spotless after cleaning.
