Great spot in London! Super central location. Lots of great sights within walking distance (Westminster Abbey, Parliament, Buckingham Palace etc..). Lots of places to eat all kind of food (British, Indian, Italien, Turkish, Portuguese etc..). Tube is nearby (Westminster and St. James). Supermarket in the building. Good area and for a city like London its very quite at night. Great living and kitchen area.
Unfortunately the windows are milky and you basically can't look outside. The bed is nice and big but a little firm (individual opinion :-)
We personally didnt like the scent of incense sticks (individual opinion :-)). The smell in the building was a bit weird but thats it. the bathroom could use some more furniture for various bathroom items.
Great alternative to a Hotel.
Definitely recommendable.
