Room is located central in the in the city and many attractions are reachable by foot (i.e. SeveralMuseums, parco retiro). Its also close to the train stations embajadores or Atocha. So it's easy to travel around the city/country from here. Just bring some earplugs, because the people on the streets are a bit loud from time to time.
Maria told me to feel as if i was at home and that i can use the living room, kitchen and bathroom if i like to. She gave me good information on how to arrive the accomodation and was a heartwarming host.
