The place has a good location and pretty clean. Jose seems to be a nice host, quite helpful and welcomed us very well. However the room is super small that I don't recommend it for 2 persons unless you are ready to sleep on air mattress (which we were quite shocked to see, though it was our bad that we didn't read the sleeping arrangements thoroughly, BUT it's not in the pictures either) and facing difficulties to move your ass around.
He also has another room listed in airbnb which he claimed to be the same size and can also accommodate 2 persons. So BEWARE of these two similar listing. Considering the value for money, there are many better options available in barcelona in similar price range (especially for a couple or 2 persons).
For a solo traveler, I would highly recommend this place.
