I was at an industry conference for a week and decided to stay at Yuha & Richard's place. They were very accommodating hosts and had exceptional, quick, communication.
The place was a perfect place for two and had a very warm atmosphere. The rooftop patio was very nice, I used it every day.
As far as the location, right in the heart of De Wallen and near many things to do, transit options, good food, and lots and lots of cool canals and architecture.
I would definitely stay at Yuha & Richard's place again if they would have me. :)
