Mosaik is fine. My room came with a foam topper on the mattress, so it was probably the most comfortable bed I've had in Pattaya. The cleaning regime is strange, as you have to request this & sometimes they still don't show up. When having a different guest every day, having clean towels matters.

Flamingo has been a good budget option, but I've not stayed there for a few years. They were sill open last month, but I have no idea where they market the rooms now.

Holidays Home hotel is directly opposite the Mosaik. I've not tried this.
