We had a fantastic stay in Paula's apartment. Her self check-in instructions were very clear, and the space was literally sparkling clean when we arrived. Her responses were always very quick. The neighbourhood is fabulous, just off Calle de Atocha that connects you from the train station, up near Puerta del Sol, and further along to major neighbourhoods in the city. It is minutes away from the Prado and Reina Sofia, and just a block from one of Madrid's most famous tapas streets (it actually turns into that street!) The only considerations are to watch your head in low ceiling areas, and prepare for the 4 flights of stairs. However, my friend and I commented multiple times that the walk up was 100% worth it for the safe, clean, and perfectly located apartment. Just a little thing to throw in is that Paula even has Netflix set up with a profile for Airbnb visitors! So many details. I fully recommend a stay!
