We rented this flat for two adults and two kids (under 10) for 3 nights. We had clear communication with the owner, easy check in/out, and the flat was exactly as pictured and nice and clean. It felt chic, yet comfortable, without having to walk on eggshells worrying about what the kids might get into. It had everything we needed and more; there were even beach umbrellas in the closet. No surprises - except for how convenient it really was to everything. Walking distance to many restaurants, bakeries, grocer, the train, metro stations, the parc, museums, cathedrals, everything! We walked most places, using the metro a few times (like to La Sagrada Familia), and used the taxi only to and from the airport. We were worried about catching a taxi at 7am to leave, but it was very easy just by walking towards the train station. The stairs are manageable with children and luggage (trust me, I had a BIG suitcase). I would recommend this flat without hesitation to friends and family visiting Barcelona. We were all sad to leave.
