Excellent location, but the apartment needs a refresh and cleaning crew needs to do a better job. Communication and check in were smooth. Apartment is a good size for a family of 4. Nice building with a very pretty lobby. There were a few things that were disappointing. We found a random pill on the floor and hair in the master shower from prior guests. Towels were very rough and felt like sandpaper (in prior reviews someone mentioned same issue a while ago and it hasn't been addressed). No bags in garbage bins in both bathrooms. Only roll and a half of toilet paper for 5 day stay. No oil, pepper for cooking, only about 20g of salt. Many plates and bowls are chipped. Blankets had yellow stains on them, yuck! Listing shows a patio/balcony - there is none accessible from apartment. You can hear and feel Renfe trains going through the tunnel/station which is directly under the building. Our California born children thought it was an earthquake at first. Oh and having exact amount in cash to pay tourist tax is not very convenient, it's 2022, everyone is taking cashless payments now.
I would recommend owners to pay closer attention to upkeep, maintenance and cleaning crew. Until then I wouldn't recommend this apartment to friends or family, despite absolutely great location close to so many things in lovely Barcelona.
