I stayed in Andreas's appartment for a month while I was learning Spanish. This appartment looks exactly the same as the pictures, new furnished. There's 2 couchs in the house, one is located in the living room and the other one is on the 2nd floor(that one is perfect for chilling with friends).
The appartment is bright enough during the day so it is perfect for doing homework. Also the location is great, bus stop in the corner, few blocks to subte. Also you can easily buy your food to cook, there's a vegetable store in the same block, bakery, meat shop and supermarket are 1 block away.
Safe area, quiet and convenience. I am highly recommend you to stay here if you are going to visit BsAs.
