Great location and nice apartment for a relatively good price.
I wouldn't recommend the place during winter months due to a really bad isolation (actually a pretty common issue in Barcelona old buildings) and not good enough heaters in the place.
Also, the neighbour downstairs is really picky and has 0 tolerance for any noise, which is a huge issue in old buildings as this one (really noisy floor). Follow the host's advise, and do not stay here with young kids.
