I have quite literally run out of epithets in praising this place... It is beyond stars and checklists etc. it is well and truly... resplendent !! In the five years we have been using AirBnB and HomesAway, this is far and above the best urban residence we have ever stayed at. Period.
Spacious, high-ceilinged, generous... once you close the doors behind you, you feel like visiting royalty. There is an inner courtyard with a gas built-in barbecue grill that brings light and fresh air that, by itself is worth the price of admission. The rooms are large and well furnished and the overall feel is one of carpeted quiet. One bedroom faces the street which can be noisy but not usually during ( Argentinian ) sleep hours.
Everything is furnished and decorated abundantly, lovingly and artfully. It is a real home (...of the rich and famous may I add !! ) rather than a commercial enterprise. The result is that you feel you are living in a distant era of opulence... and that was, for us at least, a big part of getting to know Buenos Aires.
The location is excellent... within walking distance of several sights such as the Teatro Colon and the Obelisk and nearby parks... myriads of taxis circulating at the next block.
Special mention should be made of Rodney's on-site manager... Varme. She literally outdid herself in making sure we had everything we needed before we even realized we needed it. It's a great help to know you have someone reliable and conversant in understandable English a phone call away.
I have been racking my brain to find something that was not 100% perfect and I think I found it. If you're into cooking at home the ( otherwise excellent ) selection of kitchen knives needs... sharpening.
( P.S. We have never, ever found sharpened knives at rental residences :-) )
