Antonio's apartment is within a short walk from Atocha station, so it was easy to reach from the airport, or if arriving via train. Whilst there we didn't use public transport at all, we walked everywhere, to all of the main sites.
The apartment is on the second floor of a residential block, there is a lift but currently not usable. The apartment is an internal one, so it was quite dark as the windows access the small internal courtyard, you could not see the sky, and had no idea of the weather outside!
The apartment was perfect for my husband and me; a lounge and kitchen area with everything you could possibly need, although we didn't cook, only made hot drinks. The bedroom had plenty of storage for all of our clothes and a very comfortable kingsize bed. The bathroom with a large shower had also been recently refurbished like the rest of the apartment. Everything was very clean.
As the apartment had no external windows there was absolutely no traffic noise. Unfortunately on our last two nights we were prevented from sleeping till late due to noise from another apartment, we had been told there was a rule for quiet after 10.00pm, although obviously this is beyond Antonio's control.
Overall a comfortable convenient place to stay.
