Big thanks to Flavio for a great experience in Barcelona. Apartment is perfect located and so much places are on walkable distance, on first sight is litle tiny, but soon you feel comfortable and it really has everything that you may need. Only I couldn't find the key for the balcony on the lower floor (which is shown on the photoes and looks perfect for breakfast or evening drinks :) ), hope this was my mistake and it's accesible.
Wish at least the same fun as me of everybody visiting BCN and staying at Flavio's place!
