Lola is the best host I have encountered - warm, communicative, attentive, and generous. This location cannot be beat!! I walked everywhere, even though it is so central that on3 can use both buses and the metro system. The room I stayed in was spacious (she rents two other rooms in the house but they seemed spacious as well from my quick lookaround), as was the shared bathroom. I stayed at Lola's for almost a week and would definitely book it again if I'm back in Madrid. :)
