Lila's place is amazing. The building is very cute and you can feel that it's part environmentally conscious community. You have a very private area, the rooftop gives you amazing views of the area and the plants add a nice touch that you can also enjoy in January. The apartment is well-equipped and has everything you need for a short or longer stay.
The area (Código 2) feels very local and charming, there are very nice places to eat and grocery stores close by. It's also walkable (around 20 to 30 minutes on way) to the very popular areas Roma NT and La Condesa.
I would definitely stay at Lila's place again.
