Chateau Est Takamatsu is about 10-15 minutes walk from Takamatsu station or 5 mins by car. It is best for solo travelers who look for a cheap stay without much expectation.
It is quite old and run down (AC do not work well) , but during spring time just open windows and air is fresh.
Uncle from front desk is very friendly despite such old property.
For families , I would not recommend this place, since it is nearby groups of love hotels. It is dark and you have to cross a main road at night , which is not a good idea for families or single ladies.
I have stayed in other hotels in Takamatsu and certainly this is not the best. However, if all cheap stays are booked and you just need a place to stay for a night or two, this hotel can be a ok choice.
