We spent 2 nights on the Lotus with a group of 14 and it was an excellent alternative to a hostel or hotel. The location is a little further from the centre of Amsterdam than we had hoped but access by bus is easy and it's only about a half hour walk. This is more than made up for by the great communal space (beer on tap!), friendly atmosphere around the other boats and general novelty of staying on a 125 year old sailing ship.

Olaf was very accommodating and relaxed and helped us with everything we needed. We would definitely stay on the boat again if we returned with a large group.
