I stayed from 28 Dec-3Jan and it was the excellent experience on my journey.
The flat is clean, well equipped and like in the description. Location is perfect that just walk 10 mins to Westminster Abbey and Big Ben. 3 mins to go the nearest underground Pimlico, bus stop is on the opposite road which 25 mins to arrive Regent St., town centre.
The host Yu welcomed us with hospitality and helpful. Its worth the best as I came to London 3 times.
