This penthouse is amazing and is really covering the top 3 floors of the building.
The place is very clean and the 3 patios allow very nice views, especially for sunset. The hot tub on the roof is a real gem :-)
The location is perfect. There is a brand new mall (distrito arcos) just across the street with some food outlets (Wendys, Pain Quotidien and smaller stalls like a Crepe and Hot Dog place) and of course a lot of clothing stores.
From here you can also do the open bus hop-on hop-off city tour (490 ARS/person, they only accept cash).
Ralfs Check-in was very personal. He took a lot of time to show us all the sights and good restaurants in Buenos Aires on a map.
Highly recommend this place!
