We stayed at the Magnolia Hotel Oct. 31st throught Nov 3rd and again November 7th-8th 2012 while visiting our daughter who is studying in Buenos Aires.
The service was excellent. Every person who worked at the hotel was attentive to every detail and extremely helpful. The people who worked at the front desk spoke english well and would arrange restaurant reservations and advice on places to visit in the city. It was very comforting knowing that we could rely on their help.
The rooms were large, quiet, clean, comfortable, and nicely decorated. We stayed in 2 different rooms and loved them both but particularly the rooms in the back off the main road were quieter.
The breakfast was very good (pastries, fresh juice, coffee, tea, fresh yogurt, fresh fruit) and you can purchase additional food (eggs for example) if you want a heartier meal.
The location was in Palermo and within 2 blocks you were in a great shopping and eating area.
Also on either corner of the street the inn was located on (Julian Alvarez) there is a great cafe and ice cream parlor. One block up there is a bank and ATM.
If in Buenos Aires again I would not hesitate to stay in this hotel.
