The appartment is very conveniently located. It is just a 5min walk from the beautiful Atocha railway station (where you get dropped off by the airport express bus). The Prado museum is less than 10mins walk away and the plaza mayor 15mins walk. There is a large supermarket 5-10mins nearby as well as numerous bars/ restaurants locally. It is situated in a lively neighbourhood and i felt perfectly safe walking around it at night as a solo female traveller.
The appartment was very clean and smart with all needed amenities and very good wifi. I loved the top floor balcony. I found that i was not disturbed by street noises at night.
Raul was very quick at replying to my messages prior to my trip and he was waiting for me outside the appartment when i arrived. He was very helpful suggesting places to eat in the area and sent me messages checking how i was during my stay.
I would definately recommend a trip to madrid and a stay at this air bnb
