Having visited London on many occasions for leisure, I must say that the location of the Citadines, Trafalgar is second to none.Taxi cost £8.00 from Euston Station. The embankment pier for the thames clipper is a couple of hundred yards to the left, trafalgar square a couple of hudred yards to the right. Travelling with two teenage children, the citadine apartment layout ideal i.e decent sized double bedroom, ample kitchen with dishwaher, bathroom, wc, living room with television(freeview chanels) cd player, table and chairs and a large settee which doubles as two good sized single beds. One negative point is that the carpets and decor are a little tired and need updating but this is outweighed again by the space in the 'apartment' (in central London!!). It was also very clean.
Just on the corner of Trafalgar is a little 24hr tesco shop so we stocked up the fridge fairly cheaply with fresh baguettes, ham etc. London can be very expensive with two burly teenagers constantly starving!! Also for a hearty low cost breakfast there's a Garfuncles opposite and best of all....next door to the citadines is the 'Sherlock Holmes Pub' with very reasonably priced traditional meals and great beer (have a look on the net!).
On this occasion we visited London to attend a late night concert at the O2. I pre-booked tickets on the Thames Clipper Express from Waterloo to the QE2 (O2)and of course back again. The Waterloo stop is just over the *jubilee*bridge?? which also has pedestrian crossing again only a few hundred yards(& lots of others going the same way) Honestly, could not have been simpler.
If it is a romantic break you are after, then this is NOT for you but if your sightseeing with family or with friends visiting shows or O2, I dont think you'll be disappointed here.
