I had booked a double room through airbnb using the 2 guest filter when searching
When I arrived with my boyfriend I was told that I had only booked for one person in a double room and so therefore it was not available.
So we asked what we should do and the host said it was OK if we paid more money for another person.
So we paid an extra 20 euros. We were then told it wasn't in the same building, but just down the road.
We got to the next building and it did not look as advertised. There was no four poster bed, no paintings on the ceiling and just was not the accommodation I was hoping to stay in.
If you plan to go alone, should be fine. But if you have 2 guests make sure you both confirm on the booking and that the booking says 2 guests.
A pity, because we both really wanted to stay in the glamorous room that was advertised.
