Great houseboat at great location (except for the view, because it is in an industrial zone). We enjoyed the really great electric boat, used it to go down the river towards the center or to visit one of the recommended restaurants by the river (who were having a private company, so you may want to phone ahead of time). The river traffic was really relaxed.
The mobile WiFi device was excellent and such a small and nice service, especially for non-EU visitors (which we were not, but it still made our kids happy).
A nutria swam by twice and we also met a nutria mother and her baby on shore. Even saw a catfish just relaxing close by in the river...
Easy to ride with Uber or Bolt, and rode home once using Lime steps. Public transport also fine, but with four people the cost for Uber or Bolt taxi is almost equal to public transport.
