What a wonderful stay in Mexico City! Gaby's apartment is in an easy to find and centrally located in the city - which is great for how large the city is. The building itself is incredibly convenient - with access to shopping, a gym and a pool. The building also has 24 hour security, so I always felt good about coming and going from the building at all hours.
Gaby's apartment has all the essential equipment you need, as well as extra blankets and linens. If you're missing anything, the convenience of the shops and delivery services like Ubereats will bring you whatever you need.
As others have mentioned, there is some noise even on the 7th floor - but you're in the middle of an incredibly busy city - so you should have that expectation going into this. I never found myself unable to sleep or relax - and if I did, using the outdoor terrace that's on the same floor was great for a quick break. If you're looking for an simplified stay - I recommend Gaby's place.
