This is a cool experience but be clear on what you are signing up for!
The location is fabulous! It's near the Central Train station and an easy walk to the tourist attractions. But also realize that proximity comes with a true urban experience. This is the Central Marina, not a quiet back canal, which means you are adjacent to a major road (loud all night!) , next to large hotel (Lights on all night), and if your neighbors (who actually live there) choose to sit up until 2 am talking on their stern it sounds like they are next to you. Because they are.
Our second night it rained so it it was quiet and calm (Lovely!!) so it can go either way. Basically it's a genuine marine, urban experience. People in the marina were really friendly, fun and lively.
It really is a boat so it smells a bit musty and one of the curtains even sported some genuine mold!
There is not a queen bed. There are three single bunks.
I couldn't reach Ton before we arrived with a simple question about early check in. Then when I arrived, I had trouble reaching him again. I tired text, Whats App and phone but maybe the fault was mine. It was crazy hot and perhaps I was doing something wrong, Eventually I did get him through the app but it took awhile.
Overall, this was good experience and so despite the "surprises", I rated it a 4 out of 5. If you are onboard with what you are actually getting, you will enjoy it. (Bring ear plugs, eye covers, and if its hot, a fan!)
