This apartment is advertised on Airbnb but let through a company - great service. The guy who met us and gave us the keys etc was very friendly and helpful. He was also happy to let us check out at a later time then advertised (as long as you plan this in advance). The apartment itself was perfect - 4th floor with balcony and view onto the harbour. Two single beds in the bedroom and a double sofa bed. The kitchen was fully equipped and towels were provided. The apartment has wifi & a TV too. It's only a 10 minute walk from La rambla and a 20/30 min walk from Barceloneta beach. Three of us stayed there comfortably. It was our first trip to Barcelona and we had a great time!
