We had a nice stay in Lucas's place. The location of the flat was amazing. Near to everything, such an easy connection to everywhere in Barcelona and nice places around, however, it was a little bit crowded. The place was so noisy specially during the night since its very middle in the city. The room doesnt have heating system and no windows, so if you travel during winter time, keep in mind that you cant leave the door to the balcony open, and it will be completely dark. We enjoyed staying in Barcelona and he was such a nice guy.
