I stayed there for two weeks, and overall I'd say that this is a great hotel for the price I paid. Pros: it is well located in a safe neighborhood, it is near to a shopping mall, it is near a variety of restaurants (walking distance), and the most touristically places of Buenos Aires are at a short distance of driving. Hotel is clean, the room service is daily. Breakfast is daily. Staff is extremely helpful, they help with transportation from airport to the hotel, they also help with money exchange, all for a small fee.
Cons: my room was a little bit noisy during the day, it sounded like noises of construction from the other side, at night it'd stop. Also, the shower door isn't blocking the water from splashing outside of the shower.
Overall, I'd recommend this hotel, and if i have to go back to Buenos Aires I'd book a room again.
