Alexandra was most welcoming, to the degree of meeting me at the tube from Heathrow to save making a change with my luggage, when she was unwell. It is most convenient for that airport.
Although quite a trek into Central London, the location is quiet and pleasant. The room itself is excellent, up to the standard of a 4 star hotel room. It worked extremely well for me and I have booked again, but be prepared for two flights of stairs if you have much luggage.
Highly recommended.
