Sundabakki is a wonderful place to stay - I can't recommend it highly enough.
The guesthouse itself is immaculate, with tidy rooms, very comfortable beds and a communal lounge/breakfast area with huge windows that look out towards the sea and let in lots of light. If you feel like staying in for the evening, there are big sofas and TV, and there's also a computer with free wifi, or free connection to the network if you have your own computer. There are tea/coffee/toast-making facilities in the kitchen, plus a dishwasher, fridge and a microwave - although you're not allowed to use the oven. We didn't eat breakfast here as we'd brought our own stuff with us, but it looked really good - toast, chesse, salami, cereal, fresh fruit, juice, coffee etc.
The best part of all this is the hostess, who is absolutely lovely, and made us feel so welcome. She is an incredible cake-maker, too, and insisted on giving us delicious homemade date squares to take hiking.
