Fed the local cats and chickens before leaving our stay (after getting partial refund) and drove into San Juan.
Walked around a lot of the town including the two forts and interesting streets. San Juan was the first port / fresh water after ships crossed the Atlantic, so was heavily defended by the Spanish for 400 years. There were loads of large iguanas in the fort gardens.
Checked in to our Air BnB and then wandered a bit more, stopping in La Factoria bar. Retired to the roof top terrace of our hotel to watch the sunset and the planets align.
