Me and my sister (22 and 18 years old) are planning a vacation to Barcelona. I went to Barcelona twice, but my sister has never been there. Last year we went to Lisbon, but she couldn't stand the heat so much and the beach was quite far from lisbon. So she had the idea to stay in a place close to Barcelona, close to the beach and probably a little bit more 'fresh' than staying in the city itself. So we found a apartment in Mataro, 40 minutes from Barcelona. Is it a nice place to stay? Or do we have to search for a apartment in Barcelona itself because it wouldn't make a difference?
