I'll be in London for 5 days with my parents (3 people in total) from Aug 18 to Aug 23, 2014. I will catch a train to Brussels on the evening of Aug 23. I've been looking at places to stay for about a 100$ with an upper limit of 150$ ... but hotels at that price for 3 people seem hard to find.
I looked at AirBnB and some places are quite cheap. There are many places in Croydon that seem to be cheap - this one for example (https://www.airbnb.com/rooms/507218?checkin=08%2F18%2F2014&checkout=08%2F23%2F2014&guests=3&s=oKkr). It takes about an hour to get there. I'm not sure its worth it - but the savings are huge.
What do you guys think? How easy/hard is it to get to the major sights in London from Croydon? And is it safe to walk...if we get back after dinner?
Alternatively, what areas are "budget hotel" areas (I read Kings cross, St pancraas and Bloomsbury) but its not super cheap as such. Thoughts?
