It is a nicely decorated and spacious apartment with a nice balcony! We travelled with our 7 month-old baby and it was very convenient - there is a bath tub for babies and a baby bed. The kitchen was well equipped. There is an elevator, so no problem for a stroller. It is a relatively calm neighbourhood - especially considering noisy Barcelona!
As a previous guest commented, it is true that one has to ascent a street but the street is not very steep and we found it was not a big deal.
Anna welcomed us, she is very friendly and explained everything we needed to know. We definitely recommend staying at her apartment!
