I didn't find time to write this review, but as they say "better late than never" :-)
We stayed 10 days in this house and we really enjoyed our stay.
The house is really clean, elegantly furnished and have all the amenities you could need for a rental and more (I really appreciated the amazing collection of cooking books).
The location is perfect, just a few minutes walk from the downtown but in a quiet area . If you have a rental car, there is no problem finding a free parking (all are free during the night) and during the day it's easy to find one in the streets near the house.
I was a little worried by the check in process but everything went well.
Roald is very kind and available to give you some advices (if you need) and answers quickly by email.
So, I really recommend this rental and I think we will come back in this house if we return in Reykjavik.
