Maria & Rina's apartment is lovely. The apartment itself is clean, modern, and elegant. There are lovely homey touches with artwork all over the apartment, pretty dishes, and wonderful conveniences like a coffee maker (as well as coffee and tea in the cupboard), an electric waterboiler, and a microwave. There are also books and a chess set available. Maria and Rina answer questions quickly and are very helpful in general. The apartment gets a bit cold in December, but there are two electric heaters available and blankets around the house. There is also a lovely balcony that looks out onto the street, but which is shaded from view by some pretty trees. You can also hear soft sounds of live music from bars down the street while sitting outside. Regarding noise--during our stay (just after Christmas), it was mainly quiet other than the usually noises one hears in every city, except for one night, during which there was a party down the street. That night (a Tuesday) it was very loud, but Maria and Rina provide the guests with earplugs, and it is something one has to anticipate when staying in a popular area. The location of the place is wonderful. La Condesa is a gorgeous neighborhood, with a ton of bars, restaurants, bakeries, and convenience stores nearby. It is busy, lively, and hip. It is also easy walking distance to the castle, as well as some open markets (about 20-30 minutes), and to Roma Norte (which also has incredible restaurants). In short, our stay in Mexico City was terrific, and I would easily stay in this apartment again!
