My 4-week stay at Buddha Bar was a total pleasure. Ralf met me the first morning after arriving Buenos Aires and the very pleasant drive from the airport. I think that is a must especially after the long flight and the usual airport hassles. Ralf's group at BA4U manage several units all with the most capable assistance of Marcello and Tomas. They immediately fixed a brief electricity problem as well as a short-lived hot water issue. Ralf's good advice on money exchange and minding attention paid off in no safety issues for me on the streets. I strongly recommend Las Pizarras as one on the best restaurants during my stay and it's only a few streets away. Also you should like Rietti, a block or so further.
