It's one of those places that will stay in your memory forever. The surroundings are AMAZING: mountains, glaciers, the Viedma lake, the view of the Fitz Roy (cloud permitting), condors, flag-shaped trees, Patagonian skies, you name it.
The grounds are very well kept and inviting, right next to a river (its water is drinkable!), surrounded by trees. The lodge is super comfy, warm and beautifully decorated, the bed super comfortable, and the food unbelievably good and of highest quality, prepared from scratch.
Last but definitely not least, ALL the staff is genuinely friendly and caring, and makes you feel at home.
Come prepared for the wind/rain/snow, though (you can get all of that in one day, including lots of sunshine). That's part of the Patagonia's charm :)
All the walks and horse rides are different but equally spectacular: a guided hike/horse ride to the Laguna Azul (16 km round trip), a guided hike by the lake, a guided hike to the Punta del Viento peninsula (brace for the wind!), a horse ride to the neighbouring estancia Los Hermanos, a guided hike to the Laguna del Morro (24 km round trip)... I honestly recommend all of them :)

One cannot say enough good things about Helsingfors! Most of all, the staff makes you feel like you are visiting family. The house itself has a warm and inviting feeling. The building has a cozy common area in front featuring a wood fire that the staff constantly attends to. There is a bar that provides refreshment at any time. The dining area is intimate and provides a beautiful view over Lago Vedma.

However, it is the staff that makes Helsingfors the wonderful place that it is. Of course, they tend to your every need, but they do so out of genuine concern and friendliness. Chef Nicholas prepared amazing dishes and was exceptionally accommodating to special requests. The server and bar tender, who was also named Nicholas, has a great personality and was consistently attentive in providing refreshments, tending to the fires, and serving the meals. Arianna did a great job keeping the facility clean, comfy, and inviting. And finally, Justina was amazing at keeping everything running smoothly as well as being the guide on several of the excursions.

The highlight of the trip was the horse ride and trek to Lago Azul. The scenery will leave you breathless, especially when you crest the ridge and Lago Azul first comes into view. This area is a photographers dream. Damian, the horse handler, and Justina, our guide for the day, did a great job ensuring that we were able to enjoy this experience at our own pace without ever feeling rushed.

If genuine, inviting, and comfortable hospitality in an amazingly beautiful part of the world is what you seek, you will find no better experience than Helsignfors.
