Very nice for fairly basic accommodations - large room, clean, nice bathroom, washer and dryer, very good cable, solid enough internet but a bit inconsistent. There is no elevator, so you're going to be humping up the stairs. The people are nice, there's a coffee shop downstairs, and some interesting street food right out front at night. Didn't use the pool on the roof, but it was nice up there.
The location is just off of the north end of the walking street and on a side street that features a number of go-go clubs, so there's that to consider. For me that meant walking north several blocks to find decent places to eat, etc., but not a big deal. The room, on the 3rd floor overlooking the street, was very quiet, so not a problem from that standpoint. If you're in Pattaya for the nightlife it's a great location.
