We were three adults and a 1 year old who travelled to Barcelona for a long weekend away. The flat was great for us, having space and being able to have our todler running around inside and outside on the deck. Having a small child with us it was great that the flat allowed us to stay in a few evenings as well - with the kitchen and close by supermarkets cooking was no problem, and we the adults could enjoy a glass of wine on the terrace after the little one was put to bed.
Lovely and friendly neighbourhood with supermarkets, botiques and cafes.
Ana (host) has been super responsive in all communications, and very accomodating - being Scandinavian, we asked for single duvets in stead of one double duvet in the "parents' bedroom" and she went out of her way to make sure that got arranged.
The only thing we wish we had done differently, was to gain a better understanding of public transportation options to the beach and gothic quarter. We walked, and with a baby with a short attention span it was a bit far - we should have gotten a bus or metro a few of the days.
