We stayed for one night as we were passing on to Seville the next day.
The location of Christina's flat is fantastic - very central easy to find your way back home, close to the metro, shops, taxi and the hustle and bustle of Madrid life.
Christina did not meet us there ,but left the keys at Bar Loreto, if you speak Spanish it's always advantageous. Finding the property was a small task - due to the number system, after 20 minutes we found the flat. We were situated on the fourth floor, a small flat with two loft rooms accessible by ladders (if you don't like heights or ladders - this property is not for you).
We arrived by 6pm - it was very warm so air con was on straight away.. What I like about the flat was we were only staying for a night so it's very convenient for that, and despite Christina not being around she was very easy to access via wifi.
Thank you so much Christina
