Staying at Carlos was like visiting a long-time friend, we felt comfortable from the first minute of our stay.
Our plane was badly delayed so we arrived 1 in the morning. He didn't complain about it, showed us our room and the bathroom and we all went to sleep. First morning he gave us a detailed introduction to the flat, and an even more detailed introduction to the city. He gave us a map, marked the main areas on it and explained their attractions and what to look for. He even recommended the best route to take when visiting the city for the first time.
We didn't meet much, because he was away working and we were out in the city sightseeing all day. When we all were at home he was in his room making the whole flat available for us.
The place is exactly as described. The bedroom is comfortable and really quiet, we could sleep well with balcony door open. Location is excellent, beach is cca. 15 minutes walk, subway station is less than 5 minutes and takes you to downtown in less than 15 minutes. There is even a bar on the corner of the block serving excellent croissant.
Carlos and his apartment made our 4 days stay really enjoyable. We will surely choose him as host again when we return to Barcelona.
