1. Sofia is an amazing host - super responsive and accommodating.
2. The location is unbeatable. Everything you need is nearby but Roma Sur is quieter than Roma Norte and more residential. It's only a few blocks from Centro Medico metro.
3. The apartment was very clean when I got there and I really appreciated that she'd left a few things from previous guests that could be useful - nothing gross, just extra shampoo, lotion, books, coffee.
4. My only complaint is that some things in the apartment were not in great condition - the space heater was falling apart, the lamp would fall off the desk if you even touched it wrong, and the clothes drying rack was broken in a couple places. Worst of all, the sink tilts away from the drain, making it really hard to clean.
TLDR: Wonderful but for the price I'd expect nothing to be broken. 4.5/5
