倫敦住宿問題

It depends on where exactly you are looking to stay in London, it can be pushed for a price below £30. However, if you are not fuss, there are some around £30-£40 but not in central london.

Check out the website below, I use it sometimes when we stay out late. They are Bed & Breakfasts and hotels, I wouldn't even go for hostel if you want to stay alone.

There are photos for each hotel on the website and make sure you book the one in Zone 1 so it won't cost too much for travel.

I think your price is too low for central London, are youYMCA member, if yes, you may go to their website and check it outside London stay.

aveage price for B & B in London single room £50 per night.
