Simple, clean guesthouse. Proprietor is like everyone i've ever met in 4 trips to Reykjavik: genuinely nice, feel like you've known them all your life.
I have no complaints about the room; I did think it included a TV in the room, but it was actually in the lobby of multiple room, of which mine was one. No worries; I was way too tired to watch it anyway.
Included breakfast was skimpy, but again, not a huge problem for me. Nice to have coffee and some toast or cereal before you start you day.
YMMV, but this room was perfect suitable for me and the nature of this one-night stop in Reykjavik.
