Thanks to all friends who recommended and gave advice about Taiwan.
Level of English spoken is ok.
update: not the vast amounts of bottled water (waste of money and resources, and the empty bottles pollute the environment) as in Thailand.
Only drawback is hotels are more expensive then I'm used to in Thailand, however there are hostels in Taipei below 500 Baht that are fine for me (obviously I can't take anyone to my room). And I like brown skin (even Thai-Chinese are too pale for my taste), Taiwanese boys are lacking in that department.
Opposite experience in Taipei. I wanted to withdraw money in main railway station, entered PIN and amount, but only a receipt in English (not enough for me to understand what was the problem) and Chinese came out, but no money! After staring at the screen and tapping the cover of the money slit several times, I realized this will not work. I went to the counter and showed receipt, cashier immediately told me that their ATM cannot process foreign credit cards and called another staff to walk me to an ATM that can.
Overall, from all my travels in south-east Asia, Taiwan is the optimum of civilization, reasonable prices and cute boys. Singapore comes second (my visit to Cruise Club was devastating: http://christianpfc.blogspot.com/2014/11/cruise-club-singapore.html) and as a city state less area/volume/population than Taiwan.
Update: see here as well
