It's impossible to leave anything but a glowing review for Alexandra and her fantastic accommodation.
The rooms are immaculate and comparable to a hotel standard. Good showers with decent pressure and water always hot, TV, Wifi...
Plenty of shops and restaurants nearby and transport links to Central London are convenient.
Safe area, friendly but not intrusive hosts, super clean and comfortable ensuite rooms, I don't think you could ask for more, especially for the price.
