If you are coming to Ushuaia for 3 nights, then Isla Bonita Suites is THE best accommodation the town has to offer. Mabel and team will make your stay worth everything, and they certainly deserve 5/5 or 10/10 stars.
First, the hotel is secure and easy to access for guests on their own, thanks to Mabel and her team. Great wifi that works in the whole building, and you can exchange USD here if needed. Mabel and her team are very communicative via whatsapp and super accommodating to make sure you are set up for success with tours, buses, etc.
Second, the rooms are spacious, clean, accommodating. I stayed in a two-room suite with 1 bathroom, 1 kitchenette with all proper kitchen items, at least four heaters, two smart TVs, bay windows with great views of USH. The hotel provides coffee and tea and some spices so you don't have to spend a fortune on cooking.
Third, the hotel is in the perfect location just off the main San Martin street and walking distance from a grocery store, taxi stop, shuttle bus terminal. When you check in, tell Mabel what you want to do (the National Park, Glacier Martial, Laguna Esmerelda, etc.), and she will get you to the right place or person.
Incredible service, sleeping and experience for my 6 days in USH.
