We enjoyed lovely four days at the boat. Simon and Sarah were super friendly and gave us some advice what to do in London. Sarah welcomed us and explained us everything very well. The cabine was big enough for three adults staying for 3 nights. However, if we had stayed longer, the cabine would have been to small for us. The toilet is for sharing with sarah and simon which was no problem. Taking a shower around midnight was ok too. They have a chemical toilet which was no problem for us. Still I think it's good to know. If you don't know what it is, inform yourself about it and make sure it's ok for you before you book. It was a great experience and we would recommend it.
