I rent out my condos short term (minimum 2 weeks) in Jomtien-Dongtan Beach in Pattaya, Thailand. The condo location is right next to Pattaya's gay beach -- a very fun spot, where the nightlife is wild, fantastic restaurants, and the beach is actually quite nice as well.

Spcifically my View Talay 5 condo is directly on the gay beach, while my View Talay 1 condo is a short walk away. I'm a gay friendly owner. I have had many gay singles or couples rent my units.
