My husband and I stayed here for our honeymoon in the beautiful Buenos Aires. The apartment was quite welcoming, with a chic aesthetic and comfortable furniture. The Palermo Viejo neighborhood was just right for us: plenty of great restaurants and amenities a short walk away, and we got to know the neighborhood easily. If you are not interested in taking a taxi, subway or walking for a while to get to a lot of the city, I would recommend maybe Recoleta or Monserrat. San Telmo was quite a distance, even with the subway. We love walking and the subway, but radio taxis were also relatively cheap.
Don't miss Don Julio, a popular and good value parilla just blocks away. It was busy when we went around 8pm on a Monday, but we got a glass of free champagne while we waited and the food and service were more than worth the wait. There's also a nice café off the beaten path at Gurruchaga and Beruti that's cheap, homey and great for breakfast.
Daniele was quick to respond to our messages and overall it was a great experience.
