I personally have not used the services of the Plaza Hotel. My friends who used the Plaza's services were very pleased. My friends have good impressions about the comfort of the hotel and the staff!
In my opinion, a hotel without stars will do for business travelers.
It was clean, warm, there were towels, the bed was comfortable enough, but there was nothing but soap from the toiletries. Breakfast - you can't go hungry, modestly, but tasty.
