TL;DR: This was a fantastic stay, I highly recommend it!!!!!!
I thoroughly enjoyed my stay! The flat was lovely and lived up to my expectations. Alejandra was a fantastic host and her patience and flexibility when I needed extra accommodations were impressive and outstanding, I can't thank her enough. I felt comfortable, supported, and welcome for my entire stay. The location is absolutely amazing. I was able to walk anywhere in the city center that I needed to go very conveniently, and if I wanted to take the metro, there are a variety of stations nearby. The location has the perfect combination of local places, touristy spots, and comforting fast food for when I was in a pinch. I did not realize that the flat is immediately behind the San Miguel Market, which was an extra bonus for my stay. Whenever I needed something to eat I would either walk right outside to the San Miguel Market to try some authentic Spanish cuisine, or I could run downstairs to the small store right below the flat where I could buy food to cook my own meals. This was a fantastic stay, I highly recommend it!!!!!!
