We stayed 2 nights at the Palace Hotel Arusha. We were in room 205 which looked out at Mount Meru, but we couldn't see high up it because of the clouds.
The room had a queen bed, TV, small fridge, an electronic safe, A/C, and shower only.There was a pot for heating water in the room. Being on the 2nd floor, we walked up the stairs most of the time, avoiding the long wait for an elevator.
A couple of things weren't up to par. For example, there was only 1 robe in the closet. And we only had one bath towel the first night. The light in the bathroom needed to have a switch on a receptical flipped before it worked.
But they gave us cookies at night, and the service in the dining room was friendly. They used a fluffy blanket (comforter) on the bed, which I hate, as you are either too hot or too cold, depending on whether you use it or not.
