We stayed at Beatriz's place for 4 days, and she was very helpful and communicative during the entire stay. She also provided suggestions on commuting in Barcelona and also some local food suggestions which was great!
The room was big and spacious with ample storage and the bathroom was also roomy.
The only small hitch was that the room was a little cold and did not receive any direct sunlight. I'm sure this wouldn't be a problem in Spain summers but since it was winter, it was a bit chilly.
But overall it was a very pleasant stay and is definitely value for money.
PS - You will be greeted by a very sweet and friendly co-host - Pipo, Beatriz's dog. It was definitely fun having him around :)
