We stayed in a 1 bed apartment in downtown Reykjavic and it was perfect for us as a couple. Open lounge and small kitchen area, good size shower room, bedroom, hallway and separate porch area to store shoes and coats.
The area was ideal and 15 minutes walk to the BSI terminal, which was the meeting point we had chosen for a few excursions. The area felt safe and was generally very peaceful. A decent sized supermarket about a 3 minutes walk away, ideal.
The actual apartment was great, nice, simple yet modern decoration, all the basic amenities (like kitchen utensils, hairdryer, spare towels).
Our only criticism was the cleanliness - there was visible dust on surfaces and we found hair on the bed and in the sink in the bathroom. This was a shame as it did make us question the cleanliness of the apartment and so we wiped down everything before using it.
Also during our stay, some other visitors moved into the apartment above us and were quite heavy footed and noisy (even past 23:00, which the apartment guidance asked guests to be mindful of). But that was beyond anyones control - just something to be mindful of! All in all, we had an amazing stay - thank you Reykjavic4you Apartments!
