Below is an extract from that site showing Regents College (in a red circle) and Baker Street Tube Station (the name is in red and black) SSW of Regents College.

To walk from Baker Street tube station to the College, take the exit that gets you onto Marylebone Road.  Turn left out of the station, pass the London Planetarium and Madame Tussauds and take the next left into Regents Park (York Gate).  Walk straight on across York Terrace and the Outer Circle, cross the bridge over the lake (more a like pond to Americans) and turn left when the road ends on the Inner Circle.  Regents College main entrance is well marked about 20 yards along on the left.

The buildings in blue are places of special interest.  Just South of Regents College on the Marylebone Road (the big green one) are the Planetarium and Madame Tussaud's Wax Museum.  Just North of Regents Park is Cecil Sharp House - the historic home of the English Folk Dance and Song Society (EFDSS), England's equivalent and forefather of CDSS in the US.

N.B.There is virtually no parking at the College.  What there is is "first come first served" and you will be VERY lucky to get a place.  Parking on the streets in Central London is all metered, short term and very expensive.  There are parking garages but they are few and far between and also very expensive.  The short advice is don't bring a car into London .  The traffic - and taxi drivers - are a nightmare to those not used to it, quite apart from the fact that they drive on the left and all the sign conventions are subtly different.  The good news is that the public transport systems are extremely good.  In fact, most Londoners do not even own a car and rely entirely on tube and bus.
