I extended my stay in Mara's apartment, and as I said in the other review, this is a comfortable and perfectly located apartment which has Netflix and all necessities.
For local attractions, I recommend the Bellas Artes Museum and the Museum located at the former Naval Mechanic's School, which details abuses of the military dictatorship.
There are many restaurants in the area, I recommend Santa Evita and Carneros. Also many craft beer places, La Birreria, Bier Hof, Trinity, Klub Polaco and many others.
