BYD Lofts is a very nice place. They have a several story-high cascading glass fountain and a nice restaurant downstairs. The rooms are huge, with a very nice kitchen and each room has a table and 4 chairs on the balcony. There are a few last minute hotel sites that sell BYD Lofts, I think you could get 80 euros a night, so about 3600 baht give or take. The pool on the roof is nicely done but small and is overshadowed by the condominiums between BYD and the beach. The staff are very friendly too. Do note that, there is construction going on nearby (where isn't this the case in Patong these days?) but the rooms are pretty quiet.
