The room is very well located (2mn away from the subway in the trendy Gracia district) and offers all the comfort one can expect. We found the bed particularly comfortable.
A couple of things to note: the room is not quite soundproof, which could be a problem if you are a light sleeper.
Also, the shower is really good but it is quite tiny and therefore we would not recommend this room for plus size guests.
Communication wise, John was quite proactive and helpful although we did find him less receptive when we had to move our travel dates due to COVID.
