The best host you could ask for, very friendly, chill and communicative right from the start. The room is big, has lots of space and is very quiet. The location is also great, right next to Montjuïc which is a very peaceful place but also close enough to lots of bars and restaurants and good access to the rest of the city by various transport options.
I echo all the other reviews for this listing; Miquel himself is a great guy, he'll look after you and give you all the tips and advice you need to navigate Barcelona, I 110% recommend people to stay here.
