Surprised this place hasn't for a mention yet as it's less than 50 metres from Nana entrance and is priced at between 1100 and 1400 baht per night.
The 6 rooms (2 on each floor serviced with a lift) are all clean, modern, have cable, fast wifi and key card access.
With a small coffee shop on the ground florid it has no other facilities to speak of but it's a great budget option in the heart of the action and beats a lot of other places at similar price.
I also stay at Phachara Suites, Dawin and Dream if I want pool access, but usually if just staying for a night or two before either Pattaya or flying back home I'll take the Blanket & Bean
