We stayed at the Nahuel Huapi twice, a few days apart, bookending a trip to San Martín de los Angeles. We found the staff very warm and helpful in all respects. The breakfasts are large and with a good variety of fruit, cereal, pastries. The coffee, however, is weak and tasteless. The wifi is fine in rooms facing on the street but weaker on the back. However, it's much quieter on the back, as Bariloche has a problem with noisy late night motorcyclists, as the local newspaper admitted during the time we were there.
