If you are looking to stay somewhere in Barcelona that is quiet, off the beaten path, and not full of tourists, this place is great. We stayed here for about a week, and everything worked out perfectly. The host was very helpful with getting us settled, providing recommendations about restaurants and things to do, and helping out with travel arrangements (such as scheduling an early morning taxi to the airport for our departure).
We found the apartment to be exactly as advertised. Everything was clean, spacious, and comfortable. The outside porch was a plus to enjoy the nice weather in the morning and early evening. Although we didn't do any cooking, the kitchen is well-equipped if that's something you're interested in using.
The location is superb. There are tons of shops, restaurants, and plazas within a 5-10 minute walk from the apartment. The neighborhood is mostly residential, so we really felt like we were living in the city as opposed to being surrounded by tourists in one of the busier areas of town. There is a subway stop less than a 5-minute walk away, so it was also convenient to quickly get anywhere in the city.
Overall, I would definitely recommend this apartment for a great value in a quaint neighborhood in a phenomenal city. We very much enjoyed our trip and look forward to returning to Barcelona in the future.
