I'm going to sheffield to attend a courses and would like to know
if Cutlers are a good hotel to stay in or if anyone could recommend a good hotel in the city centre between 50-60 £ included breakfast.

Cutlers is ok - where is your course ?

Don't know the Cutler but I've stayed in the Bristol (http://www.hotel-bristol.activehotels.com/THE) a couple of times and that was good (and pretty cheap)

The course is in Dronfield but I reckonned there's a bit more to
do in the evenings in Sheffield, right?

Is fargate a good place to go shopping or does everyone
go to meadowhall?

bit of both really - meadowhall at the moment is full of kids on holiday
