This is a great apartment with a unique and stylish concept. It was very clean and was just like it appears in the pictures. If you're staying with small kids, you just need to be careful with them going up the stairs and being by themselves at the second level.
The location of the apartment is great, since the metro and a 24 hour super market is just less than 5 minutes away. We hardly had to use the metro because all the major areas (Plaza Mayor, Puerto del Sol, Gran Via) are 20-25 minutes by walk. As for Lola, she is an amazing host! She greeted us at the apartment, gave us all the information we needed and more, and was super responsive throughout the trip.. even when we messaged her late at night! Thank you Lola for your hospitality and all your help and tips during our stay! :)
