I'm a 38 y.o. girl originally from Barcelona, living now in Calella, 60Km far away from the city, 1h by tren to the Barcelona center.
Calella has a nice beach and you can relax in this town, but at the same time, one has plenty of bars, restaurants and shops and activities to do, so it's not boring at all!!
I live in a 3 bedrooms flat, so you'll have your own bedroom and the flat has a nice and big terrace where I almost spend the whole time. You are free to do whatever you like. I'm quite friendly, easygoing and respectful. Of course I do expect the same :-)
