We stayed with our one year old in early September in Sidney Port Marina. The location was fantastic, not too busy and we loved sitting on the top deck, looking out at the other ships.
Note, this listing is for an agile person. We were climbing in and out of the boat and had to duck to move from room to room. I am 5'4" and managed to bang my head a few times.
There was a coffee maker, toaster, microwave and BBQ, no hot plate or oven. Showers at the marina were $3. The water was hot and the facilities were clean.
Nicholas was a good host, very communicative. If you are looking for a unique airbnb experience, this is it.
