You want to come to BCN for some days or for a long period so Victor's flat is the best option. Firstly, it's clean cozy flat with a great terrace where you can relax in the evening and do exercises in the morning. Secondly, it's located in a good area (2 min to the metro to go to the center)without awful nosy tourists but with everyday life of Spanish people and with small nice cafés. And, thirdly, it's a really great host! Victor is a very friendly, calm, responsible Spanish guy. I lived with Victor a month and I can say he is the best flatmate I have ever had. ) Thanks him a lot! I was lucky that I chose this place!
