Stayed here for a week while doing a workshop in Barcelona. The apartment is very nicely decorated and perfect for one or two people (more than two might feel crowded).
The one I thing that really bothered me about the apartment was a strong sewage smell throughout it. When I asked the host about it he assured me that this was a problem in many apartments in Barcelona, especially in this neighbourhood. I understand there's not much you can do about this, but I think it would bother most people staying in the apartment. It was quite strong.
I chose the location because it was very close to the studio I was going to, and also the price was lower than other parts of the city which was great for a long stay. It is also very close to a metro station and not a terribly long walk from other parts of the city.
Next time I would probably chose an apartment closer to the main street of the neighbourhood which would have made it easier to find a good place to eat and get some groceries and other essentials. It also feels a little sketchy when you arrive (even the cab driver was hesitant to leave me there on my own when I arrived), but I think it's pretty safe for the most part. Just a bit deserted on weekends as there are a lot of offices and studios in the area. Overall it is a nice place for the price and well mangaged by the property company.
