tl/dr - a spacious place, in a great location, and with an amazing porch.
Wake up in the morning, make an espresso, sit on the porch, and enjoy a relaxed morning. Starting the day slowly on the porch of this apartment was a true sign of a vacation for me.
After that, I spent my days roaming the streets and enjoying Madrid. The place was in the middle of the things I wanted to see in Madrid - Reina Sofia Museum in the east; Plaza Mayor & San Miguel Market in the north; El Rastro flea market in the west; and the Tabacalera in the south. I couldn't ask for more.
Oh, and a bonus - at the end of the street, on the corner, there's an amazing bakery. Oh, the smell of fresh bread...
Thanks Clara & Amir for your hospitality & service.
