I stayed at Grianne's home for one night and I would do it again if I had the chance. The location is a 15 minute drive from the airport and I recommend you look the address up before going, since the house can be a little hard to find, considering most of her neighbors don't have numbers on their doors.
The hosts are the nicest people! They are VERY welcoming and go over the top to make you feel comfortable or satisfy any need you might have. They are very easy to talk to, provided breakfast, towels, etc and even helped me out when I realized I had left my phone in the taxi that I came with, which I will forever thankful for.
The place is super practical, very clean, the location is great and the people that host it are so warm that you'll just want to go back :)
