Hi Jaky we visited this museum recently.
It was only very small, and felt more like gallery of ancient artefacts rather than a history museum.
We were there for an hour or so and felt like we had plenty of time to see everything. If you pay for one of the private guided tours when you arrive you would probably want to allow a little more time. There are some signs in English but most only give basic information like the age of the piece and where it was found.
The garden in the centre of the museum is also a nice relaxing, green, and sweetly fragrant place to just sit and chill out. about 5 years ago
