Yaiza and Aspasios company were great hosts. Very professional and very responsive. The app, once you get used to it is pretty straightforward.
Our flat in the area of Poble nou, was 2 min walk from the metro and very close to nice bars and small restaurants. Although not centrally located, which we knew, it was 30 - 40 min walk from all the main destinations.
The flat is ideal for a big family or 2 small ones. highly recommended.
