Wow! What an experience. Staying with Wamme was definitely a highlight of our 10-day trip, and our large group LOVED it. The small rooms force you to stay in the common area and hang out, the kitchen was fully equipped, Wamme was wonderful and we had a great time!
Things to note: it is a 30 min ride out from central station, but well worth it! It's well connected with trams running frequently, so it wasn't at all an issue.
