This place deserves 10 stars. Our experience was so good, we decided to extended our stay instead of traveling around the island. The room was very clean and spacious. The bedding was premium and very comfortable. The bathroom was very clean, and also spacious. The kitchen also had everything you need for a quick fix. They have a small fridge, and a dishwasher. The room had a steamer and a blow dryer. I was traveling with my daughter and we always felt safe. The staff was very professional, I can’t say enough good things about them and specially Miguel. They made our trip better with their kindness and professionalism. We got completely breakfast goodies in the room and bread delivered to our door every morning. The location was also perfect. Walkable, quiet during speeding hours despite the construction, we were not disrupted. I recommend staying at Reykjavik Residence Apartment Hotel 100%.
