I stayed at Jaquelina's place for a week. It's a great location near restaurants and walking distance from shopping in Palermo as well as public transportation to other areas of the city (e.g. Plaza de Mayo). In such a lively city, the location is central while still quiet and safer than many other neighborhoods. Jaquelina is a great hostess, very attentive and ready with suggestions and tipps for a great stay in Buenos Aires.
