We stayed at Bianca's place for almost one week. The place has a great location where you can find good restaurants and everything you need for a comfortable stay. It is near Recoleta and downtown and if you need to take an uber / taxi, it is not expensive since the location is really great.
The apartment is perfect for couples, very comfy, great shower and has everything you need to feel like home. There are markets, restaurants, stores and public transportation around there.
Bianca and her mother were extremely friendly, helpful and their recommendations were simple amazing!
