Very comfortable apartment in a phenomenal location; there were only two of us but Alex's place would be perfect for a family with up to four kids. I would only comment that the open layout doesn't afford a lot of privacy. The location in Gracia is in the heart of a very vibrant and fun neighborhood, with small pedestrian streets and large open squares offering a variety of independent shops and restaurants, as well as many small groceries stores open late and really anything you might need. The immediate area is foodie heaven, with very high quality just about anywhere we went (the large squares like Placa del Sol are more hit or miss foodwise, but great for a coffee or a beer); the bakery Mistral right around the corner is notable as one of the very best anywhere, bar none. Tourist highlights are easy to get to; it's a quick 10 minute walk to Passeig de Gracia and maybe 30 minutes to the Gothic area/Las Ramblas. Gaudi's Parc Guell is a few blocks north and his Casa Vicens is one block north. Sagrada Familia is 25 minutes on foot. The subway is right nearby as well.
Alex greeted us in person and was very friendly and helpful. The unit includes a nespresso machine and a large variety of coffee capsules sold at cost, which is a great service to have. The unit is well furnished and equipped, with a fully-stocked kitchen and a laundry room in the back with a washer and dryer. I would have been happy to stay several more weeks. Oh, and the wifi rocked as well, no connection or bandwidth issues, worked great for online live classes and streaming netflix.
Thanks Alex, we had a great stay!
