We arrived into Madrid late at night and Irene was really nice to come and meet us and gave us an intro to the area (the restaurant she recommended which was round the corner 'Juana la loca' turned out to be our favourite!).
The apartment is in an excellent location, with tapas bars just downstairs along the street. Lively on the streets but nice and quiet in the apartment. It is an easy walk to Grand Via, Plaza Mayor and the food market.
It is nicely furnished right down to the little details and is well equipped for a night in if you want to cook as well. Just note that there are no lifts to the apartment and it's a pretty narrow flight of stairs so leave your big and bulky luggages at home and you're good! :) would definitely recommend and book a stay with her again if we're back in the city.
