We LOVED our stay at the Butterfly Guesthouse! Jon is a wonderful host and our upstairs apartment was cozy, clean and comfortable. The location is perfect: 5 minute walks to the harbor, the 'old city' and Bus Stop #1, (super convenient for tour and shuttle bus pick-ups). Our apartment was sunny with a private bathroom and kitchenette- perfect for the 3 of us. Coffee, tea and milk were kindly stocked and fresh towels and trash removal were provided twice during the week. Food is fresh and delicious in Iceland but expensive, so we appreciated being able to cook a few meals; that said, local restaurant options were varied and excellent and every meal was fantastic. We did not use the radiators in August, but hot water was plentiful and comes from geothermal sources, (renewable energy hooray!) The hot water everywhere smells a bit like sulfur coming out of the faucet but leaves NO smell on skin, hair or clothing. (Just don't use for cooking or consumption). Cold water is sourced differently and is safe to drink in Iceland. We needed no cabs or public transportation in the city and our furthest walk to the BSI bus station for departure Covid tests was 20 minutes through a beautiful park, (testing is quick, efficient, hygienic and professional- prebook appointments online). Again -Jon is an A host who met us on arrival. We loved our trip and look forward to returning to the Butterfly Guesthouse!
