Stayed here for five nights, and it was very nice!
Fabiola does only speak Spanish, so I did not get to know her as much as I would have if I'd spoken any Spanish. And Cristina (who speaks English as well) was only there the last night, but both of them were super nice! Very helpful an discreet. Clean and comfy home.
The location was perfect, a quiet inner courtyard, but still not more than 10meters to the Gran Via and all the shopping, sights and restaurants. I will go back to Madrid again, and will try to stay at their place again then! Can not recommend this enough!
