We had a very nice stay over at Eltjo & Liselore - they are extremely nice and helpful.
Living on a boat for a couple of nights was a nice experience and I would recommended it to anyone interested in trying an alternative housing.
Perfect for couples, but might not be OK for other type of travellers: as you can see in the photos, the shower/toilet are integrated in the room itself (no real doors to separate).
Good breakfast.
Located close to city centre, everything is reachable by foot (15-20 minutes walk).
