Sergio meet us at specified time in his apartment. It isn't so far from Atocha rail station so we walked from it for 15-20 minutes. There are an underground station and a supermarket near the apartment (Plaza Tirso de Molina). Sergio's apartment is very clean and comfortable. It was very handy that the kitchen contains such products as sugar, flour, tea and even olive oil. The only small nuisance It was a little cold in the flat in early february. In all the rest we were satisfied. Thanks!
