We recently stayed at the Hotel Del Centro and were disappointed with the size of the room; mostly disappointed in the size of the bathroom.
Positives: Great location on Via Roma (about a 5 minute walk from the train and bus stations and walking distance to many sights), free internet (slow at times but mostly ok), friendly staff, breakfast included.
Negatives: Small room and bathroom. While sitting on the toilet my face was literally in the sink. The shower was very uncomfortable because of the size (I'm 5'7", 130 lbs and it was uncomfortable). To be fair, I think some of the other rooms are not this small. It seemed like the room next to us was significantly bigger. Also, the walls are paper thin; it was impossilbe to sleep in past 7 am. The only other negative is that they don't have any english language channels but I guess this isn't a big deal.
I would recommend this hotel only if you're able to book a bigger room (or room with a bigger bathroom) and if you're a very heavy sleeper that can sleep in very noisy conditions.
