We're a family of four (2 kids age seven, husband and wife). We stayed at Anna's while on vacation to Spain. The location is very clean (the sheets smelled great), it was spacious (2 bathrooms) and we slept comfortably. The #1 thing about Anna's place is the LOCATION. You can see Sagrada Familia from the window! There are plenty of small bars, restaurants, supermarkets, etc., nearby yet at night, it's not really too loud.
The kitchen was cozy but had everything we needed. The main bedroom was very spacious and the entire flat is flooded with external light :)
I recommend this location.
