This place was great! Raul was a great host, available for any questions and gave quick responses. He also spent a half-hour just going through highlights of the city he thought we'd like.
The location was great for my wife and I. The street had a lot of life - bars, cafes, bakeries, and easy access to the Metro. I consider it at the "southeast" of all that I wanted to see. Close to the Atocha Station (we took a trip to Barcelona too) and Retiro Park.
The most "northwest" point of the city was just under a 30 minute - Hotel Rio with Club 360 (beautiful spot for sunsets), where Templo de Debod is located.
The balcony was great as well! Nice view, pretty architecture visible, and extra nice when the sun was coming up or going down. Sunset can be seen from the kitchen as well!
Just note for anyone who likes to walk everywhere like us that to get to Gran Via or much of the places WE wanted, they're, what I would say, is uphill from here. So, we often started our night with an uphill trek. Not a problem for us, but something other travelers who aren't as mobile may want to consider. Just remember, again, close access to the Metro.
Other than that, there was a coffee pot if needed as well as Italian-style coffee maker which we used often. Also a cool tea kettle. Pots, pans, and spices if needed. Hot water for the shower/bath was great. Hair dryer worked well for my wife. The apartment is built for you to recycle everything just like the rest of Madrid.
I definitely recommend the stay here. Price and location were perfect!
