Alvaro's apartment is amazing and great for long term stays. I lived there for about 6 weeks in Autumn. The floor to ceiling windows in the living room are just magical (the photos really don't do it justice) and the place is toasty warm in the cooler months thanks to the radiator heating. I also have to mention the back patio - probably my favourite place. It is well protected from the wind so even as it got cooler I could sit out there and catch some sun pretty much all day and well into the afternoon. The apartment is also right in the mix of things in a great neighbourhood full of bars and restaurants. At night there was some noise heard every now and then but considering where the apartment is located I thought it was very quiet (especially by Buenos Aires standards). The apartment has double glazed windows everywhere so I suspect this helps. I cooked a lot and the kitchen was easy to work in and was pretty well equipped. The bed was very comfortable and the shower had great water pressure - what more can you ask for! Alvaro himself was a pleasure to deal with. He speaks English very well and was very responsive to any questions I had. Check in and check out were a breeze and every now and then Alvaro would check to see I had everything I needed. All in all it was an outstanding stay and am hoping to stay again later in the year.
