When I went on a vacation to Argentina a few months ago, I stayed briefly at Posada del Olivo, and I must say...I've never had a better experience at a hotel before. The staff were very friendly (and, luckily for me, knew a fair bit of English), the grounds were beautiful, and the owner, Sebastian, did everything he could to help me enjoy my stay in his hotel, including directing me along an amazingly gorgeous route for the following days that I wouldn't've taken otherwise (and helping me find accommodations along the way). I cannot speak highly enough of this hotel and the people running it.
