Daniel B. Families - 7/12/2026 Confirmed reviews ALL

Good breakfast, good location, good pool. Awful sound isolation and rooms were not good, especially considering the fact that I paid 1000eur for 4 nights. Would not recommend. Sound isolation is terrible. Entire family couldnt sleep until 23:00 every night. When asked to change the room I was told that its not possible because it was fully booked. When asked if they could tell my neighbors to be quiet nothing effective was done. When I went to my neighbours myself, and told them that we can’t sleep, only then one neighbour stopped being loud at night.
