It is a beautiful city with a rich colonial history. It carries in town centre some European style building from the 18th century. We g0t there at sunset and the first mission was to find a cheap motel. We found this one fairly quickly, and we could even let the bikes in the lounge !
Luckily, October seems to be a fiesta month in the city, and on sundays plenty of street shows occur, with typical dancing and costumes.
Day or night, the city is quite pleasant.
