Santiago
Happy House Hostel http://www.happyhousehostel.cl/
The friendliest service at any hotel I stayed at during this trip. It is a hostel, but you can still reserve a private room if you so choose. Location is great and the building is beautiful. It's a renovated mansion converted into a hostel. Absolutely lovely.
Pucon
Hotel Antumulal http://www.antumalal.com/
Probably the most gorgeous hotel I've ever stayed in. Definitely worth the splurge, which really isn't that expensive compared to the typical hotel prices in the US and Europe. You will want to spend a full day just at the hotel alone exploring their beautiful grounds and taking a dip in the lake, weather pending. The architecture is simply splendid. Check out the restaurant too!
Punta Arenas
Hostal Fitz Roy http://www.hostalfitzroy.com/
Since there were 3 of us we rented the apartment. Furnishings are basic, but the owners are wonderful. They were incredibly accommodating and helpful. You truly felt like you were staying at someone's house rather than a hotel.
Puerto Natales
Hotel Oasis http://www.hotelesdelapatagonia.cl/ficha.php?cod_des=2&cod_hot=16
I would say this hotel was fine considering we really weren't there much. The best thing might have been the bizarre gnome collection they kept hidden in plants around the hotel. But one night we stopped at another hotel for an amazing dinner and I really wish we had stayed there: Indigo http://www.indigopatagonia.com/en/
ARGENTINA
Iguazu
Hotel Esturion http://www.hotelesturion.com/
This hotel had a great pool and an amazing poolside restaurant with a fantastic barbecue of roasted vegetables and an assortment of meats. The grounds were lovely as well with a very serene sitting area by the river.
Buenos Aires
Art Hotel http://www.arthotel.com.ar/
I loved this hotel so much that I stayed there again on the second trip! The location is perfect, right in the Recoleta. The rooms are gorgeous: exposed brick walls, high ceilings with canopy beds. And the price is a steal!
