We stayed at Swiss Cottage for 5 nights during our 3-week-vacation in Malaysia. We stayed in a beachfront hut, the location was beautiful though the sandflies were kind of a bummer but of course that's not the guesthouses fault, they even provided anti sandflies lotion. The AC was very noisy. The matress was not very comfortable, I was under the impression it hasn't been exchanged for quite some time.
There was no room service though the hp states there'd be room service every 3 days. The breakfast was very simple and in times the portions were really small. Like 2 slices of french toast and 2 small pieces of apple.
The water filter is great and helps saving money and cutting down on plastic.
All in all I'd say it's a beautiful place but the price of almost € 50 is very steep.
