We (family with son of 5) had a 5 five days stay in the very pretty Silvia's house. Coming from France, we have appreciated to leave our car (even if it's difficult to find a free place in the streets), to use only the subway very near of the house and few stations to the city-center, and a supermarket at less than 100m. The house is very spacious, clean and plesant. Silvia is very friendly and can give all necessary advices on the places to visit in Barcelona.
