Hiya,
What a beautiful time to come and visit London. I live in North London so recommendations may be a little this side of the river......
-restaurants duck and waffle in heron tower -pricey but lovely views and great interior, mem and laz and Gallipoli for cheap eats along upper st in islington, banners in crouch end for good grub if you are up north.
- lovely things to do : watch a performance in regents park open air theatre, see if there are any concerts on the lake at kenwood house, walk around Hyde park, Colombia rd market on a Sunday, Broadway market on a Saturday, clissold park and cafe then a stroll down church st ( possibly eat in yum yums! In stoke newington). Go to the Albert hall for a show if you can afford it.go to Ronnie Scott's for some fab jazz, lovely food and very atmospheric night out (pricey though...)
- best galleries - serpentine, tate modern, saatchi gallery and Hayward.
- best museums - British museum, v&a, natural history and science museum (the last 3 are all in walking distance of each other)
I would steer clear of camden unless you have a spare hour to look round, I work there and it can be a bit grotty unless you want some market goods.
Love St. Paul's cathedral, tate modern and design museum walk (all closeish together too)
Only hotel I know is hotel Hoxton. www.hoxtonhotels.com
Don't get to stay in hotels much due to £ and have a house here!
Get a timeout mag as soon as you get here or look online - they list everything!
Get an Oyster card for the tube so can can travel cheaply, a week long travel card would be best.
Please feel free to ask any more questions or query anything. Us Londoners can be a very friendly bunch so ask away and I hope you have a welcoming and sunny (here's hoping) stay!
