i think the entrance is about 150-200 meters from the tube station ish, the building is directly across the road from warren street tube station (it's got a glass front so is really easy to spot when you're still getting your bearings when first get out of the station and onto the street) but the entrance to the hospital is a little bit further up the road.
i've no idea how long you'll be there though, i've only been twice and once i waited several hours and the most recent time i was seen within 30 mins, i think it depends on how many patients they are behind with and so if you have an early appointment you tend to have a shorter wait.
i hope your foot heals quickly and isn't too painful on the way there!
and keenly, i'm sorry, i've never stayed at the hospital or the hotel so i dont know. maybe you could give the main reception at the hospital a call and see if someone there knows? i'm sure they must get a lot of similar questions
i'm going to see the orthopedic department at uclh on the 18th feb at 1pm, has anyone else seen this department before?
anyone around on the same day and fancy a coffee or tea in the cafe?
