Alexia's place was absolutely wonderful and MUCH better than the pictures lead you to believe. It's situated on a quiet street in the heart of Fitzrovia/Soho, where you're within 5-10 min walk to most tube stations (Oxford Circus, Tottenham Ct Rd, Goodge St, Great Portland St, etc), lovely cafes and restaurants, Tesco and Sainsbury, and 20min walk to all the theatres. The City is 30min by tube, if you're in town for business.
The flat is impeccably clean, bright, full of light, with a gorgeous balcony. Triple-paned windows insure complete sound insulation, and there's every amenity desired inside -- stove, microwave, grill, dishwasher, towel warmer in the bathroom. Hot water is plentiful and the water pressure is great.
Communication with Alexia is a breeze, she's extremely friendly and responsive. I can't think of a single negative for this place and recommend it without reservations to anyone interested!
