I stayed at one of their apartments in Barcelona in May '13 and I must admit that the experience has been spotless. Great service, superb communication with them at all times and lots of flexibility to check-in and check-out. The put no objections to us leaving the flat at bit later than expected. The place itself was clean and exactly as it was described on ad. The location is excellent, next to the beach, Boqueria market and within 15 min. walk from Plaza Catalunya. Would definitively recommend it to anyone visiting the city. The ideal no. people in the flat is three, four max (if there is couple) although the sofa-bed is quite comfy (five people would fit if necessary).
