Walking around London

I walked a lot in London yesterday, so I will show you the way I walked.
At 9:00, I came out of my room at Dinwiddy, and went to the counter to get a card for laundry.
I thought I didn't need to pay for washing my clothes, but I found I need to pay for it by online payment.
(washing 1.5 pound? drying 1 pound?)
Anyway, I started my walking at 9:10. At first, I went to my university, SOAS. My course plan was to use Swinton St., Gray's Inn Road, Tavistock Place, go straight and turn left. However, I missed to turn to Taistock place, so I got lost... Anyway, I took 30 minutes to go to the university. At university, there were a few people. The entrance door of Brunei Gallary opened and I went in, but I was stopped by staffs. Then, I moved to the British Museum, which is located near SOAS. At 9:50, there were some tourists, and they were waiting for the open. I didn't enter this museum and walked for the west.
My parents will come this week to bring my stuffs from Japan. They will stay near Oxford Circus Station. On Oxford Street, I found there were a lot of people even in Sunday. Several department store are there but all of them were closed when I went there. After I checked the way to the hotel where my parents will stay, I returned to Tottengam Court Road and went to the South.
2 weeks ago, a senior friend recommended to go to National Portrait Gallary, so I went there. I lent Japanese audio guide (3 pounds), and went around this museum. It was interesting to look a lot of famous people's faces. However, I was not satisfied by the contents of Japanese audio guide, it was poor...
Following that, I went to Japan Center near Piccadilly Circus. It was busy. Not only Japanese tourists but also Korean, Chinese, Westerners were there to eat Japanese healthy foods or buying Japanese food ingredients. The shop was good, but expensive comparing to buying in Japan. Double or triple? Anyway, I bought some foods and a plum wine.

As you might expect, I was so tired because I walked for 6 hours including walking in the museum. So I got on Tube from Picadilly Circus to King's cross. Yesterday walk was good excise for me, but I am now  suffering from muscle ache!
