I stayed at Cititel Pekanbaru one night on my way to Riau. The hotel is located in the center of Pekanbaru, close to a shopping center. Rooms are a bit small but clean, bathroom is adequate. Bed is good, no bedside reading lights. I could not find a light switch for the bathroom light so the light stayed on all night, and with a glass door this is not very nice.
Breakfast is OK. Staff is friendly but speak little English so communication might prove difficult, but with some sign language and patience you will get there. Prices are, for what is offered, quite good.
