I absolutely loved staying in Carlos’s apartment. The bed is one of the most comfortable beds I have ever slept on anywhere and the apartment is beautiful and clean, and also has a great view from the living room and bedroom. The apartment building is located in Plaza de la Villa downtown (centro Madrid), and the legendary tapas “heaven” of Mercado de San Miguel is very easy walking distance around the corner along with the supermarket (great 3 euros cava in the supermarket!!!). Please note, if you do not like stairs (even with the elevator) this is not the place for you. Also, be sure to have your cell charged at night to use your flashlight in the hallways or so you can find the switches to turn on the hallway lights every few feet. The darkness is no joke! Carlos was very kind and responsive via what s app to let me know how to work his stove to make coffee on my last morning there. It was locked, but he explained what to press to unlock it and how to make it work. Whenever I return to Madrid, I will definitely request to stay there again. Carlos’s home is in a historic building in easy walking distance to many great places in Madrid and an Uber ride to/from the airport is less than 30 euros — fair price and convenient! Enjoy your stay!
