Sid was absolutely amazing! From the very beginning he was so friendly and welcoming. I must have bugged him a million times with so many questions and he always responded right away. He even went above and beyond to help make sure we didn’t miss an episode of game of thrones and provided us with a link to watch it. I can’t stress enough how amazing his hospitality was. We even met his dog (I was missing my dogs so that was a huge plus). Now, on to the actual flat. I know some of the reviews had some complaints like the thin walls or the other room for rent but we always travel with ear plugs so I wasn’t too concerned. Yes the walls are a bit thin but not that bad at all and as far as the other room next to ours it was being used but we didn’t run into our neighbors at all. Anytime we travel we do worry about the bed but his bed was very comfortable. The bathroom was down the hall but padlocked so it was just for us. The place is so cozy and private, the guest side of the flat is separated by a door so it feels very private. My husband also really enjoyed having a cigar out on the terrace. Sid made us feel right at home and had some nice touches like his book of recommendations, directions and water for us. His location was perfect and so close to so many things. The metro is literally right across the street. We would definitely stay here again if we come back to Barcelona.
