First off, this Air Bnb is located in the Lavapies area in Madrid. We found it central to everything we needed. It is a very young area that is home to many delicious restaurants and fun bars.
Sara was super nice throughout the entire booking process. Her daughter Barbara met us at the AirBnb and showed us around. She was kind enough to send us a very detailed list of restaurant recommendations, which was a nice touch.
The Air Bnb itself is very basic but has everything you need. We felt safe with the three doors required to even reach our apartment door. It is a small space so I wouldn't stay here if you're any more than 2 people, but for my partner and I it worked just fine. There is a small kitchen that we didn't use and a small bathroom that is typical for Spain. I would say to have no hesitations booking this Air Bnb if you're planning to spend most of your time outside exploring Madrid and want a comfortable, safe, clean space to come back to sleep in (purely because of the size of the place.) Also Sara is the most wonderful host! Thank you Sara for everything!
