We can thoroughly recommend this accommodation; great value for money, really clean, big enough with everything we needed for our stay. Also in a great location we felt like we were in the heart of Reykjavik, but it wasn't noisy at night. The support team were really helpful and responsive on email, so I didn't miss there not being a reception on site.
There is a supermarket just round the corner and a 5 minute walk from lovely restaurants and shops.
Would definitely stay here again if we come back to Reykjavik
