While Pere is very responsive to emails, we were very disappointed with his place based on the very high ratings others gave.
The positives (in addition to host's communication):
Great location, walkable to city center, shopping areas etc. Apartment is very spacious and beds are comfortable.
The negatives:
76 steps up to the apartment. Seventy-six!!! Very difficult with luggage or groceries.
Pictures make the place look much nicer than it is. Not sure what was renovated in 2015 per the description, but flat seems like it hasn't been spruced up for several decades.
There is a pervasive smell of sewage in the apartment which does not go away. Upon arrival there was an overly fragrant and cloying toilet bowl rim hanger which we found highly irritating so we removed it temporarily only to realize it must have been placed there to mask the sewage smell.
Suspect that guests who are accustomed to nicer places should look elsewhere but students might find this apartment palatial.
If you do plan to stay here, there is an amazing Pollastre de Serrano nearby for takeout roast chicken, paella, and Quijada (pig cheek I think) and we really enjoyed dinner at Tapla, only a 2 minute walk away. Neither of these are touristy and are not in city center.
