Anastasia's place was very clean and very well located. It is perfect for a small family (we travelled with our 19 month old) or small group of friends/2 couples.
There is a great little bar called Le Pata Negra in the square right outside the apartment that has yummy little bites and cold beer/sangria, overlooking the playground.
Poblesec station is right at the doorstep, and it's walking distance to pretty much everywhere if you are ok with longer walks. 15 mins to LA Rambla, 45 mins to Barceloneta. 10 mins to the Magic Fountain. Lots of great food options nearby.
We will definitely stay again if ever back in Barcelona!
