Clean and modern apartment tucked away behind the polo fields in the Las Canitas sub of Palermo. Lots of great food/bev options in the immediate area, plus all of Palermo SoHo/Hollywood a bit of a walk or short cab away.
Before booking I read some of the reviews mentioning noise. Having now stayed there 5 nights I think it's important to have realistic expectations. This is not a 5-star hotel. This is an (upscale) apartment building inhabited by others who are living their lives, including entertaining, smoking, having dogs, etc. all during hours that are customary locally (i.e. late relative to Northern Europe/North America). So yes, there is some level of "noise" from neighbors, but relatively speaking, this is a quiet building and a quiet neighborhood.
Other things to know: Memory foam bed is very comfortable. Pool is a nice, swimmable length, but is not heated. Laundry is free, conveniently located on the lower level, but there is no dryer (so wash your stuff a couple days before you have to repack to allow time to hang dry). There is also a parking garage located in the building so you be brave (or crazy) enough to drive a car in BA. 24 hour security is provided.
