Alejandro's apartment is in a beautiful location that was within walking distance to many of the places we wanted to see during our first trip to Mexico City. And if you can't/don't want to walk? Uber was an easy solution, made even easier by the free wifi at the apartment.
Really though, what makes Condesa Zapata a special place is Alejandro himself. He makes himself infinitely available for your every need, but respects privacy when you need it. He is an amazing host. When my boyfriend and I got food poisoning, he quickly brought sports drinks to rehydrate and food he knew we would like (he went to a vegetarian restaurant just for me!). I only hope we can repay some of his kindness if he is ever in our region.
The room itself was cozy and clean. We had a slight issue with our shower -- the lack of a sill made the water go out onto the bathroom floor -- but Alejandro is aware of it, and has plans to get it fixed. What's more, he sent someone to clean the room midway through our stay, and offered to change the bath mat and towels because of the moisture. So no worries.
Oh, and one last thing -- his dog, Lady, is a sweetheart, though very quiet and serious. If you're a dog lover, you will love her. If you're iffy about dogs, don't worry because you'll hardly know she's there.
Thanks, Alejandro!
