Piccadilly Line hotel

If it is just you, then I suggest the Hub Hotel Covent Garden. It is an easy walk from Leicester Square tube station on the Piccadilly Line, surrounded by restaurants and pubs and an easy walk to Soho and the National Gallery.

I have stayed at both The Nadler Kensington (at least half a dozen times) and the Premier Inn on Knaresborough Place (once). Both are a 5 minute walk from the Earls Court tube station and frequently have rooms in your price range. The prices at the Nadler can vary drastically depending on when you book.

I typically arrive on an evening flight and the hotels are an easy and safe walk. Exit the tube at the Earl’s Court Road exit, cross the street. You will see a Paul’s. Walk one block down the cross street by Paul’s. At the end of the block, turn left to get to the Premier Inn and turn right to get to the Nadler.

I like the Celtic Hotel, just kitty corner to Russell Square station and handy to a nice pub. Excellent location within walking distance of British Museum, Soho and the City. http://www.stmargaretshotel.co.uk/W_e_l_c_o_m_e.html

I will be traveling with my teenage son in October - saved $ for a long time and he can't wait to see the Harry Potter sights! We will travel back from Edinburgh and will need a hotel near the Piccadilly Line in order to get to Heathrow the next day. I've been looking at the Celtic Hotel and it is quite a bit less than some of the others in central London - is there a reason for this? I'd like to book it but just wanted to hear more about it. Thank you for any help!

The other hotels mentioned in this thread are chain hotels. I prefer small independent inns, and the Celtic fits that bill. Look up its Tripadvisor reviews and I'm sure you'll see its reputable and clean. I stay there and I refer all my friends there.

Thank you so much! really helpful!
