We stayed 3 weeks here. In terms of location, we wouldn't recommend this place for first time visitors to Buenos Aires, as its quite far from tourist attractions and a good 25 minute walk into Palermo. It would be better for people familiar with Buenos Aires already.

Pros: Close to the underground metro, and a handy overground train station (Chacarita staion, Linea San Martin) which goes to the main Retiro bus and train station, much quicker and even cheaper than the metro. Fast internet, and good hot water supply. During the December heatwave in Buenos Aires the power and water stayed on. Good building and apartment security. There are good supermarkets nearby. We had good communication from Alejandro (except when we tried to contact him about checking out, he didn't reply to our emails but showed up just as we were leaving, which was ok, as it was good to meet him). The neighbourhood seemed reasonably safe.

Cons: There were a few things broken or not as advertised. Only one element out of two on the stove worked; the advertised bicycle had a flat tyre; constant dripping from air conditioning units upstairs made it difficult to sit on the balcony. It was very noisy most hours of the day with trains right below. The bed wasn't very comfortable and felt like it was going to break - it was very wobbly. Maybe it is ok for 1 person, but 2 people was almost too much for it.

To Alejandro's credit, we raised these issues privately with him, and he was very apologetic, and has promised to look into the things we weren't happy with, so hopefully the next guests have a better stay than we did!
