It was our first time staying in a jetty, we loved the location, sitting in the evening above the water… Facility itself built by immigrants, for sure construction very simple, toilet sewage directly down to the water, the electrical water heater for the shared shower was not working- but it was o.k., warm enough for cold water. Overall we liked it very much, because it was an exceptional experience not comparable to a hotel. We stayed 2 nights. We had no extended contact to the owner, got our keys without problems and gave it back to a family member. In the other parts of the jetty were some shops, we loved the freshly prepared mango juice!
I think, there are several rooms in different buildings, we stayed in the one close to the end (not the one having the sign on the door).
Overall- perfect for 2-3 nights to discover Penang and a real special experience. Just don't expect luxury room or similar.
