Domingo's apartment along Calle de las Huertas was better than I could have expected!
First of all, the location was fantastic. It has close proximity to the Medieval part of the city. The Museo del Prado, Puerto del Sol and Plaza Mayor which are main spots are all walkable with a lot of things to see along the way.
Great Restaurants and Tapas bars dot the street, right where the apartment is found. At night it can be noisy, but nothing closing the windows can't fix. But why should you stay in at night when there is a great nightlife out in the streets! It felt perfectly safe regardless of what time we came home.
Most importantly however, is Domingo was a wonderful host. Since the beginning of our correspondence he has been very accommodating, even more so when we arrived in Madrid. I can't speak highly enough of how quirky but comfortable and homey his apartment is. I highly recommend it to all those who consider visiting.
