We had a really enjoyable stay in the camper. It's basic, but has everything you need (including a very comfy bed and a clean, hot and powerful shower). The setting is really spectacular, and we would thoroughly recommend doing one of the local walks - such beautiful scenery and plenty of cute animals to admire. I'd also recommend staying up a little later one night to look at the stars - I did it in a groggy state at 1am when returning from the loo and was too tired to appreciate it, but the whole sky was beautifully illuminated.
Unless you're after 5-star luxury, you can't go wrong with Tellic's place.
