The location of Penelope's apartment truly can't be beat! It's right above Espresso de Medianoche, a wonderful cafe with a really friendly staff, and walking distance to tons of restaurants, shops, supermarkets, and the beautiful Parque Mexico. Seriously, plan to spend all your time at the park -- it's perfect. Penelope was also sooo quick to respond to our messages, which really helped whenever we had a question. The apartment itself is small, and as others have mentioned, it's up a few flights of stairs. It's definitely ideal for one traveler, maybe two if you don't have a ton of stuff, and very affordable. Would recommend!
