Martha's apartment is really good. The location is perfect because you are literally four blocks away from Reforma Ave. and close to several restaurants, bars and nightlife (Condesa, Roma and Zona Rosa are walking distance)
The neighborhood is quiet, you can walk at night without worrying so much. You'll find a lot of people walking their dogs and having a good time. I strongly prefer this part of the city than Condesa or Roma because of that. It feels really safe and close to everything.
Now, about the apartment. You'll have everything you need. The kitchen is fully equipped if you want to cook your meals. You can buy groceries around the corner or you can walk three blocks to the nearest market to buy fresh fruits and meat.
All the decoration is new and the lighting is great, specially in the mornings. The bed is comfy and the bathroom is good too.
Our experience was great and we'll definitely book again with Martha.
