We were greeted by Inma's friend Raul, who was super-friendly, helpful, always in touch with us, and very easy to deal with.
The location is amazing, we walked to Sol (15 minutes) the Prado, Retiro (20 minutes) and more. Across the street from 1 metro, and a few minutes away from another one.
We took a cab from Atocha station, which was about 10 euro.
Very easy to get to/from the airport with public transportation as well.
There is a supermarket around the corner, and a bunch more within walking distance.
Madrid was boiling in mid-august, and the air-conditioning was a very welcome relief, but we soon found out that the apartment never really got too hot, even mid-day, and with an open window we didn't even need the a.c
Internet was great, Kitchen had lots of staples provided already.
And the best part:
Our flight was at midnight, the night after we were supposed to check out, but Inma let us leave our stuff there the entire day, and we only checked out at around 9 pm.
Really an amazing place, would definitely stay here again and highly recommend it!
