My best Air B&B stay.
Good standard, excellent service, realy clean and super good location for sight-seeing.
They allowed me to check in way early (11:10, earlier then agreed even! :D ). Communication was close to flawless, super fast answers, professional and a kind pleasant tone.
Only one small complaint;
Thin walls but everyone followed the kl.23:00 quiet rule so falling asleep was easy. Sleeping in was less so but acceptable, I whent back to sleep fast with no issue.
I recommend Valhalls rooms and will most likely use again next time in Oslo!
