We enjoyed a lovely three days at Las Balsas as part of our honeymoon in Argentina & Brazil. The lounge has a very welcoming feel and a great open fire for the chillier evenings! The food is first-class - certainly not your average hotel restaurant - and Pablo the sommelier recommended some excellent yet not stupidly expensive wines.
The rooms are not luxurious, but are absolutely perfect for a relaxing stay by the lakes - and when you consider that the area is a winter ski resort, then the rooms are certainly way above what you would normally expect in a ski hotel. What a magnificent view of the lake and mountains when you open the curtains in the morning !
Ignacio the concierge was superb in detailing, recommending and arranging trips - we went on a boat trip, hike and horse-ride and it all went perfectly. Both Pablo and Ignacio were most helpful in recommending other places, trips in Argentina - the overriding feeling we received was that they love their country and want guests to enjoy it and love it too.
All the staff were very welcoming and friendly and they could not do enough for us - without ever being imposing - they were happy to chat if you approached them on a subject.
The spa is also very good, although note that treatments do need to be booked normally the previous day.
We would certainly recommend the Las Balsas to anyone staying or visiting Villa La Angostura - it is a small hotel and therefore the service much more personal. Even if you are not staying at the hotel you can still go there to eat - and we would also strongly recommend doing that.
Thankyou for a fantastic three days - we'll certainly be coming back next time we go to Argentina.

As New Yorkers, my wife & I can be difficult - Las Balsas exceeded our expectations in every area. Our room was right on the lake. We can't wait to return, in a couple of years.
Should not be missed, if possible.

Charming location & attentive staff ... Our only critiscism was regarding the food, they should mix the "inventive" with a few simpler dishes.

Anywhere that has a blazing log fire in the gym / spa in the evenings is to be commended.

We stayed during winter time with my wife for 3 nights. We had a wonderful stay. The location is great (located besides the lake, with private beach and dock). The staff was very friendly and service was excellent. The SPA and food were both world class.
A couple of things that we disliked: the rooms are very small (except the suites) and pillows are not very good.
Overall we highly recommend the hotel.
