We just got back to California after spending Christmas and New Year aboard Jessie. We loved our time on the boat. Meg is a wonderful hostess and very accommodating. She managed to moor the boat in the place we had requested (Liitle Venice, one block fom Warwick Avenue tube station), met us upon arrival and even had a small Christmas tree waiting to greet us. When we told her we were planning to cook Christmas dinner on the boat, Meg recommended the Waitrose supermarket nearby where we bought everything we needed. Our nephew and two friends --- students in London spending the Holidays away from their families --- came for dinner and we all had a great time.
We loved the location and were greeted every morning by the geese, ducks and swans. They added a wonderful dimension to our stay. The boat is very comfortable for two people (and probably for a small family as well) and is quite elegant. We were asked by a few people if they could take a picture next to it :)
Those considering a stay aboard Jessie should remember that this is not a hotel room or a flat. It's a boat. You have to run the engine twice a day for hot water and to charge the batteries, and lighting the fire on cold days may require extra time in the morning. But we didn't mind. On the contrary, we found a lot of pleasure in carrying out these boat tasks.
We highly recommend it if you want to experience London from a different lens.
