About the cons, It is terribly difficult to find a museum: different addresses, then Sarkandaugavas , 30, then Zagera, 7. Bus stop 24 with the name "Dauderi Museum" is far from the museum, and the nearby tram stop 5 has a completely different name and it is very difficult to find the entrance to the museum, because it is located deep from the street and he's not in sight, I've been looking for him for 2 hours.
And the museum is interesting, a beautiful park, friendly museum staff, but there are few visitors, largely due to the lack of necessary information.
