Yes it is, but Tagaytay is not that close, although I could see Manila in the distance from the Palace in the Sky, the highest point in Tagaytay. In 2003, I traveled in Eastern Mindanao. I thought it was very peaceful but the people I met told me not to go to Western Mindanao. That is where most of the problems are. Even they did not go to Western Mindanao.
As I recall, Tagaytay is on the rim of the Taal Volcano. It is an "artsy" community. Years ago, I would take my navy plane into the volcano. It is just beautiful. It has a Island in a Island on an Island in the ocean. Good place to live.
