the host is quite complicated or let's say "very serious". If you rent the appartement only for yourself and will receive guests later, they will charge you A LOT for every additional guest and night. They even close doors of some bedrooms, so that you're not able to use them until you pay extra.
Karla who takes care of you during your stay is very kind though and helps you with everything you need, e.g. laundry service, tips where to go, check-out etc.
The house was clean, comfortable bed, very little hot water
