We stayed for a week in Silvia's appartement: a very nice, bright & intriguing decorated place.
Ideal for travelling with children, our 2 year old daughter liked it a lot, everything is available (coth, high chair, toys,...).
It's located in a quite, green, non-touristic area, a lovely hide out for the tourist madness in the city center in August ;-) Bars, restaurants, grocery stores, playgrounds,... are nearby, as well as metro stops Poble Sec & Parallel. Barrio Gotic (Ramblas) is within walking distance (30' more or less).
Silvia was very proactive and gave us information (about how to get to her appartement,...) before we left, nice to meet her upon arrival, she gave us some more information about the area and a map of Montejuic Parc, which you will need as it's quite a maze ;-)
Highly recommanded, we would love to stay here again, thanks again for the lovely time Silvia!
Pía, Kris & Caroline
