We enjoyed Los Pecanes. We went there during Argeninas winter in June 2012. I travelled there with my wife who needs a wheelchair, and low and behold, Los Pecanes delivered. We were welcomed at the pier and my wife, wheelchair, luggage, and myself were helped off the boat.
Our room was excellent with two large window with screens, so at night you can open them without fear of bugs and listen to the sounds of the night , the river, and occasional night sounds.
Breakfast is limited to toast and jams, but lunch and dinner are plentiful and includes a bottle of wine. The hosts Richard and Ana are helpful, kind, and fun to be with and if you don't speak Spanish, you can speak English or French with them.
Los Pecanes is not for people who look for a lot of activity or nightlife, it is a place of peace and quiet, for reading and relaxing and SILENCE. Mind you, we were there during Argentinas winter, so we shared the place only with a few other visitors.
Yes, my wife and I would go back to Los Pecanes.
