I am attempting to leave a balanced review, which represents our true experience:
Teresa is very pleasant, responsive and helpful, a great host.
Her home has many great features, the pictures and description are pretty actuate.
As others have said, it is near the metro, bus lines, shopping center and about 1 mile from a beach. However, it is also next to an auto body shop which can be pretty loud starting about 8 or 9am. The neighborhood looks to be in a transitional phase and if currently very industrial, but it is very close to the "locals" restaurants & area (Poble Nou).
The home has everything you need for a long stay (we stayed 2 weeks), however being from the US we found the beds a bit uncomfortable. The terrance upstairs is very nice (one of the rooms is up there with no AC), however please know it only accessible using outdoor stairs, meaning everything needs to be carried up and down these stairs.
All in all if you want to be off the beaten path in a up and coming area and hosted by a wonderful person- this checks all the boxes.
