This is a really lovely space in Barceloneta, very close to the beach. It is, however, a bit tucked away, so that the street is remarkably tranquil for someplace so close to the centre of the action. The street is picturesque and strictly residential, but around the corner there are many local stores and cafes, including, very close, a bakery (Mayer) with baguettes (etc) that will knock your socks off. :-)
The space is well maintained and looked after. I stayed for a few weeks, and I was pleased to see that any difficulty, no matter how small, was sorted out quickly and effectively. Also communication was friendly and easy in both Spanish and English.
The space is clean and things work well. Note, however, that there is no lift in the building. Also, this is not a large flat. The sofa would fit two at the most, there is not much spare room in the bedrooms, etc. Of course, the balcony is great for getting a feeling of space. It's not huge, but there is a chair and it can be lovely to sit out there and watch the world go by.
Note that getting a license to run an Airbnb flat in Barcelona is challenging, and there are many places rented out illegally. In contrast, this place has a proper license on display. That may be one reason why it is up to a good standard.
In sum, this place is not an opulent mansion, but it is a comfortable flat in a fabulous location with a friendly, helpful, and effective host. I hope that others will enjoy it as much as I did. :-)
