Great location overlooking the corner of Plaza Serrano. Near great restaurants (Don Julio, Chori) and bars (try the great cocktails at Parque Bar Botanico).
Downside is that the great location near bars and restaurants means there is often noise outside the window until the early morning hours - normal if you live in a city, so it didn't bother us - but don't come here if you're looking for peace and quiet.
Comically small bathroom and very small shower. Good water pressure and hot water.
Felt safe in the building and the neighborhood.
Equipped kitchen.
The host was very nice, responsive and spoke great English. Offered tips that made our stay better.
