This is a hostel in essence rather than a private residence. Three stories (all stairs) and about three rooms per floor, two toilet/shower rooms, and a stocked kitchen with nice flat ware, dishes and micro, and water kettle. The third floor has a larger kitchen and in the fridge is eggs, yogurt, milk and cereal for a quick complimentary breakfast. There's also a common lounge and small roof top patio one extra flight up from floor three. This place is managed by incredibly kind people. It's very quiet, calm, very clean and safe. Each room has its own set of keys, there's fast wireless internet.
It's possible to stay and come across no other guests or find them in the crow's nest lounge or patio. Clearly there are return guests who come for business or repeat trips to London.
It's in a great location, though the Goodge street station exit onto the street is a bit sketchy / dodgey if it's your first time here. Step away from the station and explore; it's a great arty, hip area, less than a mile from the University of London where a fantastic farmers market (meaning unbelievale food booths) happens every Thursday from noon to 2:00 / 14:00.
Week days from noon to 3:00 / 15:00 just up from Tottenham Street turn left onto Tottenham Court Road for out door food stalls 6£ for Indian, Thai, Italian, Argentinian, Mexican and more super-delish take away street food.
There's everything you could need nearby: Pret a Manger, a zillion coffee shops including: Better Coffee (2), Nero (2), Starbucks, and an Italian coffee place owned by Scicilians right next to Goodge Street Station. There's an Asian market, Stansbury's a Vodafone, and places to buy adapters, chargers.... anything and everything you might have forgotten... maybe that umbrella.
Get the (regular, the 7-day costs more) Oyster card in the terminal at the Airport and you're all set for hopping around London on the tube.
At Tottenham Circle tube station is a theater with Broadway shows: last minute walk in front area seats are only £25!!
