What reliable Bulgaria VPS hosts offering specials now do you know and can share?

If you ask me, I have seen pretty good discount codes on Hostplay.com Bulgaria VPS deals:
Use the promo code XOFF15HP and receive 15% off for all new Virtual Private Servers packages purchases.
Valid (March 01, 2018 - June 30, 2018)

Is it reliable offshore VPS host? Have you ever used their services before?
Any other alternatives for comparison?
