I had a great stay at Adriana's place!
It is indeed a very tiny place - but the space is surprisingly well layed out and especially for one person, for few days, it was perfect and all i needed! The location was great too - you have several Oxxo's nearby, there's a small park two blocks away and a bigger park just a couple blocks further. All relevant transpo is within short walk too.
Adriana was also very kind and accommodating - she allowed me to arrive several hours early so that I could rest after a bumpy night bus and was very flexible when i needed to leave an hour late as well. She brought me an extra blanket when i was cold at night and she was quick to reply to all my questions about the neighborhood!
I had a really nice time and if it hadn't already been reserved by someone else, I would've stayed a few extra days! :)
