The host is very responsive, they usually answered within an hour or so but that wasn't good enough because getting an answer and not a solution isn't really helpful.
It was freezing cold in the apartment so we asked for some extra blankets but they just said that there was no availability for extra blankets, no apology no suggestions as to what we could do just that and a sign off All best.
The same afternoon when we came back from our sightseeing we found the boiler leaking so I messaged them about it right away. They said oh yes the boiler leaks when it's heating up water, it's normal. But we got into the shower only to find out there was no hot water at all. Their instructions on how to turn the boiler on (switching fuses on in the fuse box) were incomplete or for a different apartment so it took hours for them to actually send a helpful response. The same day at midnight they messaged to say it was the guests' fault that the boiler was leaking!
