At the last minute I got Covid and couldn't travel as planned, but my friends stayed at Anna's place and she was very flexible to the new contact person etc.
They reported the place to be comfortable, clean and in a great location for gigs/the city. They couldn't work out how to use the sofa bed, but I'm sure that was them and not an issue with the sofa itself.
The place held up well considering how hot it was! Thanks Anna for accomodating us.
