We have a spacious (110m2), sunny and very quite flat with a 30m2 terrace in the centre of Barcelona, 10 minutes walking distance from the beach. The place has one bedroom and a kid's room with a doble sofa. Everything is well equipped, there is central heating and air-conditioning, high speed Internet connection, TV, etc. including BBQ on the terrace. We have a small kid and are opened to exchange with families with kids. Our flat is perfect for a family and max. 2 kids (1 master bedroom, kid's room with bunk bed).
It is situated in the lively, not touristy part of the "Eixample Dreta", just next to Paseo San Joan and the Born neighbourhood, Gran Vía and Barcelona's biggest park (Parc de la Ciutadadella, zoo). Literally everything is within walking distance (Plaza Catalunya, Paseo de Gracia, Sagrada Famila and the beach); there are 2 mayor metro lines (L1, L2) and many bus lines. There are a lots of bars and restaurants around, as well as supermarkets and cornershops.
We are a couple with a small kid (3 years). We have done more than 10 exchanges so far (NYC, San Francisco, Toronto, Amsterdam, Berlin, Granada, Edingburgh, Vienna, Helsinki, etc.). We speak English, Spanish, German and Catalan. For the summer 2014 (August) we are open to other interesting offers.
