พิพิธภัณฑ์ตำหนักปลายเนิน หรือ วังคลองเตย
The palace is easily accessible (Rama 4 road, less than 200 m walk from MRT Klong Toey), but open only once per year on 29 April.
I walked past many times, and this year had opportunity to visit.
Entry is free with guided tour in Thai (I joined the 15:00-16:30 tour), drinks and food sold outside, and books about the prince and reproductions of photos and drawings by the prince.
Information board on Rama 4 road:
Entrance on Rama 4 road (the palace is 60 m inside on the right at
13.7213709,100.5542121 = 13°43'16.9"N 100°33'15.2"E):
The palace is a rather unspectacular traditional Thai wooden house:
There was water, but now dry:
Verdict: for the average tourist, Suan Pakkard, Jim Thompson house or Kukrit house are a better choice; more to see and open all over the year.
April 28 is the birthday of H.R.H. Prince Narisaranuvattivongse นริศรานุวัดติวงศ์ (Prince Naris นริศ). https://en.wikipedia.org/wiki/Narisara_Nuwattiwong
The palace is open on April 28 for invited guests and on April 29 for general public. (Mistake in book ASA Architectural Awards: Bangkok Walking Guide, on p274 it says open April 28th.)
