My wife and I had a wonderful eight month stay in Sofía´s apartment. I work from home most days and was delighted by the comfortable desk and chair, as well as all the natural light. Even though the apartment is an interior unit, the classic 1950s building design has huge windows that bring in light through the interior light wells. Because of its interior location, it's also wonderfully quiet even though it's on a busy street. The bed is incredibly comfortable (so much so that we didn't want to leave), and the kitchen is well-appointed. We brought some of our own things to make our long-term stay more comfortable and Sofía was always more than accommodating. The apartment itself is absolutely charming - it's small, yes, but full of nice touches - and lots of plants! The bathroom in the bedroom may be a bit inconvenient when hosting, but otherwise isn't a problem. Sofía was always responsive to any need we had - and luckily those were few, since everything generally worked well. The street where the apartment is located isn't the most exciting - mostly bathroom and kitchen stores - but you're a few minute walk away from lots of cafes, markets, and places to eat (the taco spot on the corner became a favorite). It's a quiet neighborhood perfect to rest and work, but you're still only a 25 minute walk from Roma/Condesa where there's a lot more things to do.
