Me and my wife don't regret that we chose this apartment. Angeles is a wonderful host. From prompt responses to our emails before the visit, to our departure from the apartment, everything was exactly the way we had expected.
In our view, the apartment fits perfectly for a couple. No frills, but at the same time, all you need during the short stay (four nights in our case). And of course, the patio was the icing on the cake for us in sunny Barcelona even in February.
We deliberately preferred to live away from the downtown with its hustle and bustle. The district of Sants-Montjuic appeared very cozy and comfortable. The apartment is a short distance to one of the major streets of Barcelona, Parallel, with two metro lines (L1 and L5).
However, we used not only metro but also buses. It's very convenient if you know how to get where you want (our tip: download the tmb app (or explore tmb.cat website) before your trip and use all the advantages of the Barcelona transport web).
A few more recommendations for newcomers. There are a lot of supermarket chains in the city. We tried three of them in close proximity to the apartment: Caprabo (2-3-minute walk), Consum (4-5), Mercadona (~10). Our choice is the former because of the largest assortment, however prices in Caprabo maybe somewhat higher.
A lot of people have recommended the local tapas bar Can Violi. Maybe it wasn't our day, but their tapas missed our expectations. Though, it doesn't mean you shouldn't pop in and try. Instead, we loved buying fresh and delicious pastries for breakfast at Panet on Carrer d'Olzinelles (1 minute walk).
Finally, for shoppers, between L'illa Diagonal and Gran Via 2 (if you like walking, both centers within 30 minutes from apartment), we recommend the latter with >150 outlets and a huge two-storey Carrefour.
To sum up, we strongly recommend the Angeles' apartments . For families with children, or larger group than two people with close relationship, she has larger options in the same building.
