We were very happy to stay in this cosy apartment. It is in ideal location, it's spacious and beautiful.
Host welcomed us and showed us everything we need to know about apartment.
We went for a short 3day trip to Barcelona and apartment location was very important for us. You have supermarket ~400m away, Las Ramblas, Port, metro station (you can get directly to Park Guell and Sagrada from there). We enjoyed that there is a kitchen and you can make your own food and coffee (enjoy Cortado while in BCN).
For two couples or a family this is all you need - 2 separate rooms with comfortable beds + living room.
I would definitely recommend this apartment for your Barcelona visit! :)

Only thing we were missing was some oil for cooking and dish washing sponge + liquid.
I read in other reviews that people didn't have toilet paper, but we had it in apartment. Host even gave little hand soap bar and some small shampoos.
