My flight arrived a little late at 12:30 pm in Terminal 5. Immigration was easy with a short line. The officer did ask a lot of questions, especially what i was going to do for more than a month in the UK.
I found the Metro entrance to the Piccadilly line and bought an Oyster card from the machine and loaded it up. Then I went about half way to central London where my slightly cheaper hotel was located.
The walk to the hotel was about one mile. I stopped for a spicy doner along the way at a kebob place. The hotel was very basic but warm and comfortable. The Romanian hotel attendant was very friendly.
In the afternoon I went back to the tube and went to Piccadilly Circus, Trafalgar Square, and Westminster to look around. It was gray and drizzly so I didn't take any good photos.
