I stayed at Maria's for 2 weeks and had a very comfortable stay. With a separate entrance and own mini kitchen area and own bathroom, I didn't need to bother her. The bed was very comfy, and although the shower is cosy, there was plenty of lovely hot water. The room can get a little warm, but there is a window that easily opens to balance the temperature. I fully recommend to stay here. The apartment has a security entrance and there is a small cafe in the sun at the front of the flats. There is a Carrefour over the road and plenty of pharmacies - I became ill and got some antibiotics fairly smoothly. Maria even made me some hot soup! To the left of General Peron there are many highrise office buildings with lots of bars and to the right, uphill, is a street with many shops. I recommend the Irish Rover around the corner from Calle de Orense for a lovely pub environment and there's another bar around the corner with 5 beers for a few Euros. There are 2/3 metro stations to get to easily, within 10/15 minutes walk away. Thanks Maria! :)
