We loved Vali und Simona place...We travelled with a group of 4 guys and it was perfect. For me its the best area to stay, a lot of locals and if you step in direction ramblas you pass the beautiful rambla of raval and you meet a lot of tourists.
Appartment on the ground floor was really clean. Rooms are as presented on the pics and the shower was always hot and spacious.
The terrace is huge and offers a great evening chill.
Strongly recommend also because Simona was really reactive and very friendly.
