Number One Massage

I will be travelling to CHIANG MAI for 3 to 4 weeks in November and I am looking for suggestions on areas I should consider staying in. My number 1 priority is access to the mountains for trail running. That being said, I would still like to have amenities close by such as places to eat, a gym and possibly a spa etc. And I of course want to spend

I have found a number of spas in Silom but unable to find any that's all-in-one location. Does such a place exist? I'm looking for a spa that does hair treatment, facial, body massages (prefer Ayurvedic) & foot massage. Any recommendation is appreciated.
