Great place. Clean, comfortable. Loved the wrap-around windows and views from 14 stories up! Having the Alameda Jardin across the street made going out so pleasant and it was nice to walk through it to get to the Hidalgo metro and bus stops. Great location for getting transport or walking through the Centro Historico.
Good kitchen with good equipment, including dish soap, sponge and towel. Even a blender. Didn't see any olive oil or S&P but there were some other supplies left by previous guests.
There's a funky sort of supermarket called Bodega Aurrera a few blocks west of the apartment and left on Av. Banderas. It's just off Av Juarez on the west side of Banderas but hard to find because of the sidewalk vendors' carts. Plus it has a sort of nondescript entrance you might walk by without noticing.
The stores sell liquor but don't generally have good wine. I googled "Wine shops in Historic Center of CDMX" and found some wine shops not too far away.
So much to do in CDMX. Bring a good map. The tourist office maps are horrible and totally useless. The buses and metro (especially) are great and you can get just about anywhere. The Metrobus Linea 4 from the airport stops at Hidalgo station which is just across the park from Erika's apartment building. You have to buy the Metrobus card by the Terminal's exit gate #7 from a machine. The card costs 10 pesos and to fill it for the bus you need to add at least 30 pesos to get into town. You can keep refilling the card (at certain places) and use it on CDMX buses and the metro subway, which cost 5 pesos per ride, with some transfers allowed. I put 100 pesos on the card at the airport so I wouldn't have to find a place to recharge it later in town. That gave me enough to get to and from the airport, and to take public transport about 8 times. Erika can give you better information.
Didn't meet Erika in person but she was very responsive by email or text. The doorman was nice and friendly (Spanish only). I totally recommend this place!
