We had a fantastic stay in this apartment. It was well-situated, clean, very good beds, lift access to the 5th floor, quiet and plenty of light. The air-conditioning was also a godsend as there were some massive thunderstorms in Barcelona during our stay and it got very humid and sticky outside. The wifi access was first rate and very useful for researching attractions, booking tickets online and keeping in touch with family and friends. We didn't get to meet Arne, but his check-in agent, Maritxell, was very helpful. We had no reason to contact them again during our stay as there were no problems to report and we were familiar enough with the city to not need any recommendations. The check-out process was simple and straight-forward with just a key drop. ** An insiders tip: The little tapas bar, Pic-zas, downstairs from the building has excellent jamòn iberico and manchego to enjoy with a cold beer, but the little bar cafe, La Neura, on the corner of Bailén and Rossellò, which you can only find at night when it opens and they lift the metal shutters, was excellent! A great little neighbourhood spot if you don't want to venture far from home after a long day spent on the beach or sightseeing.
