Olaf and Mark's houseboat far exceeded expectations and allowed me to experience Amsterdam like I had never before. I truly enjoyed the uniqueness of waking up on the canals, living like a local, and being central to all of the shops, restaurants, etc. I walked to each of my meals, grabbed groceries at the local store, and relaxed on the patio - even though it was December!
I'd highly recommend staying on a houseboat instead of a hotel, and Olaf and Mark are welcoming, keep their unit clean and accommodating, and are very good at communicating.
I will be returning again in the near future.
