The host: Maria Luisa was an excellent hostess. She quickly replies too all messages and is very helpful with any concerns regarding your stay or even sightseeing in Madrid. She was also extra attentive and arranged for a taxi to take us to the airport the morning of our check out.
The apartment: the apartment is exactly as pictured. Artsy, clean and very spacious. After staying in several other Airbnb places throughout my Euro vacation, I must say that there is a huge difference between the agency run apartment and the ones owner occupied. This apartment is a home and it makes you feel like you're right at home. The living area is comfortable, the bedrooms spacious, the kitchen well equipped and the bathroom is large compared to most of the other places I stayed. It's truly one of the cutest apartments that I've stayed in and feels cry "Madrid".
Location: it's perfect! You can walk everywhere. I traveled with my mother who has arthritis and some issues with her knees and we walked almost everywhere. We rarely used a cab! Puerta Del Sol, El Prado is about a 8-10 min walk. It took us about 20 min to reach el Palacio Real (I took a wrong turn so maybe it's closer) the Puerta de Atocha is also within walking distance. There are some hilly streets so I definitely wouldn't hull my luggage from the train station to the apartment but you certainly can if you don't mind that. You're also within walking distance to La Latina for great food or La Plaza Mayor. At the same time, you're in a street with very few tourists and more of a local feel. If you're interested in a phenomenal flamenco show, Casa Patas is two blocks away. It was truly the perfect ending to my Spain stay. Amazing food and fantastic show! As you can see, this apartment has everything to make your Madrid stay perfect. I can't recommend this apartment enough!
