Absolutely perfect! Notably;
1. Host communication was better than any other Airbnb I have stayed at, which gave lots of confidence when staying in a completely new city
2. Apartment itself was clean, well furnished, spacious, quiet and safe. We were three couples and all the bedrooms/bathrooms worked well for that setup
3. The location was great for getting to Ramblas and then on to lots of the tourist spots. We walked to Sagrada, the beach, Gothic Quarter etc
If you are looking for a great base to explore Barcelona you cannot go wrong here, so very highly recommended.
