My family and I had a fantastic time in this Airbnb. It's located close to three different metro lines, it's walking distance from local markets, there are many shops around and it's easy to get to.
The host Paul was very helpful with directions and even helping us get a taxi for the airport. He and the woman who showed us the apartment (I can't remember her name) were very very kind and accessible.
The apartment is spacious, and having two full bathrooms for our family of five was a life saver. The kitchen was well equipped and had basic cooking items, which we gladly used the two times we ate in.
The whole place was very clean and the beds were firm but comfy. We had a lot of towels, and that was great so we could take some to the beach.
I definitely recommend this Airbnb and will consider staying there again if we go back to Barcelona.
