We stayed for 4 nights here and the airbnb was really good. The location is really great and you really feel like you are in the hustle and bustle of the city. There are plenty of shops, cafes and bars on your doorstep. As 2 female travellers, we felt safe in the airbnb and surrounding area. We got quite a few taxis which were easy to get and pretty cheap too. Buses were also cheap and quite easy to get.
The airbnb was good value for money. It was clean and comfortable. The room had most of what we needed for our stay - the fridge and safe came in very handy. The bed was comfortable and the bathroom was decent. It would have been nice to have a few cleaning products as we were there for 5 days but this wasn't too much of a problem, just our personal preference.
It was really nice to have a terrace to go up onto to get some fresh air and relax, although it did get quite full of smokers at one point, but I guess thats partly what it is there for!
Overall, the airbnb was great value for money and we would return to this airbnb if we were visiting Barcelona again, which I hope we will.
