Close enough to the centre and tube, the internet only works at the reception even if you pay for it you can't used at your room, so we felt that was very tricky!
Excellent, near to the train station, very easy to walk to and from centre
Really close to the train station (Kloten), very clean and the staff more than welcoming. If you want to go to some specific place and you don't know how to get there, they explain you and even print all the information you may need.
Very close to St Pancras and London centre
