Hello Natalia/Sergio,
We are back in the USA but wanted to drop a quick thank you note for all the help/tips you provided during our stay in Madrid. Definitely wish we could have spent a few more days. Your place is awesome and close to so many attractions/places. Having grocery store (Lidl) and metro bus station within a few minutes from your place was the best part. Would definitely like to recommend you to our friends/family who might be heading out that way. Thanks and all the best
