I stayed in Ruy's apartment when my brother and I visited Buenos Aires for 5 days. We very much enjoyed staying at Ruy's place. The apartment was clean, modern, and conveniently located. It was right next to a supermarket, laundromat, and many other shops and restaurants. My only small concern was that the wifi service was intermittent during our stay, but it was not a big deal. Ruy was responsive throughout our stay and was very helpful - he even provided us with a subway transit card to use. I look forward to the next time I can visit Buenos Aires and stay at Ruy's place. Thanks Ruy!
