I would like to recommend Doci, a massage therapist at Boston Day Spa on Bole. I have had a terrible muscle spasm in my shoulder/back and with her expertise I think it is finally getting better. The cost was 200 birr, but so worth it! And the place is as beautiful as you will see anywhere in the world. It is in the same style as their sister resort, Kuriftu Resort and Spa in Debre Zeit. I also recommend that place. Again, not cheap but if you need a reprive from Addis life, visit one of these places and you won't be disappointed.
