Karla's place was perfect! The apartment is exactly as presented, very stylish and clean. Comfortable bedding, loads of sunlight, and fairly quiet despite being ideally located in a hip, hopping neighborhood (some noise from neighbors coming and going, but really minimal even on Friday and Saturday night). It is located on the third floor, so I could imagine it gets a tad warm when the weather heats up, but during the spring we had very comfortable temperatures and there are lot of windows to get a nice cross breeze.
I can't say enough about the neighborhood- it was such a great area to wander around without a plan- you are certain to stumble into a beautiful park and countless cafes/bars/restaurants with patios full of locals. There is no shortage of good food for all times of the day, and a street market on Friday mornings where you can get delicious fresh produce, juices, crafts, and of course, tacos! Also, a 7-11 right on the corner where you can stock up on essentials such as bottled water.
Karla's recommendations for restaurants, bars, and even a walking tour near the Zocalo were spot on and extremely helpful. I also reached out to her several times during my visit to ask recommendations and she was friendly and quick to respond.
You can't go wrong staying here, I would love to return!
