I had the best stay at Hotel Reykjavík Centrum! It’s incredibly walkable- about 4 minutes from many things, around 9 mins from most things, and a max of around 15 mins from nearly every major spot in town you’d want to see. The rooms are clean, nice, and spacious. You’ll have a mini fridge, a safe, nice shower, closet space, and desk. The staff is extremely helpful and kind. Breakfast is complimentary every morning. They have a huge closet to hold your bags if you need, and checkout isn’t until 12 PM! This location is close enough to everything while also being cozy and quiet. There’s a corner store 2 doors down if you need anything. There’s also a gelato shop, seafood/sushi restaurant, 2 hot dog stands, and a food hall right down the street (2 mins). If you’re planning to spend some time walking Reykjavik, this is the spot!
