I’d go stay in Mysore for two weeks again. Or maybe Trivandrum? It was so laid back, but that was back in 1991, so it might have changed. Yes, probably Trivandrum and have a nice 28-day ayurvedic panchakarma there.
Actually I have several countries/cities on my To-go-to-list so it’s difficult to decide on a Nr 1… hm I’ll go with Singapore.
As for recomandations it’s definitely Osaka (Japan). Friendly people, beautiful castle and lot’s of other places to go to in an 1h distance. Plus I just love the dialect in that area ^-^
