Bed & Breakfasts in London

In Central London B&B is often interpreted as cheap, simple and very low cost hotel, not the small family owned run establishments with high standards and personal attention you routinely get outside London.
What family type B&B's there are, are normally more expensive than a budget hotel.

In Bloomsbury my first place to look at under the loose 'B&B' category would be the Arosfa Hotel.

The Arran House Hotel gets very high marks in the Lonely Planet London guidebook. In addition to regular private rooms, it has some dorm-type rooms at hostel-like prices. Everyone gets the full English breakfast.

The Arosfa Hotel is also near the top of the LP list.

There are dozens of inexpensive hotels and B&Bs in the Kings Cross area of London. I've stayed there many times and the location is ideal.
Walk 10 minutes to the British Museum, walk across the street to the Kings Cross station for a Tube or Train to anywhere.

you might keep your options more open for a hotel with breakfast incl. do not know about Bloomsbury as it can be higher in $ but try garden Court hotel nr Kensington Park excellent all round great price and breakfast avail. walk to most of London top spots also from here.

We stayed in the Jesmond Hotel in September. Its on Gower Street which becomes Bloomsbury Street past Bedford Square. The rooms are good, the included breakfast was wonderful, and it's 5-10 minutes walk from the British Museum. See- http://www.jesmondhotel.org.uk/
Good luck!

My friends stayed at the Ridgemount Hotel in Bloomsbury Sept 09 and were very pleased. Not listed as a B&B but it was small, served breakfast, staff very friendly and has good reviews on Trip Advisor. Enjoy your trip, Pam

have stayed at the ridgemont 5 times and plan on staying in the spring.....clean, safe, convenient to tube, great location....nice owners....reasonably price.....
