Do yourself a favor, and stay at Emi’s place- it is fantastic; one of the best Airbnb’s I’ve ever stayed in. The apartment (top floor of a 4 story building- there is an elevator), has been completely refurbished, retaining all its old character and charm, but with all the modern stylish touches you would hope to expect. The pictures are very accurate, which is not always the case with Airbnb rentals.
Location is perfect – right in the middle of El Carmen, the old historic district. You can walk to everything – the silk exchange, the central market, the cathedrals, museums, etc., are all just a few minutes away. Be sure to grab a kebab at Kebab Bolseria just across the street; have some food at La Pilareta just around the corner, and rent a bike from the place @ 100m down the street.
Communication with Emi, (and also Eva and Tanu) was super easy, and I wouldn’t change a thing about the apartment - it was absolutely perfect, and the small terrace facing away from the street was a bonus.
6 stars if I could.
