Hey,
Anything from Baker Street on that line takes up to 15 minutes to 1/2 hour depending on rush hour.
Living in Wembley is fine, most of 1st and 2nd years live from baker street to northwick park on both the met and jubliee line.
If your wondering about hip places. I'd say the west end is your place to go, but it's in zone 1 on the tube map. Therefore living at Wembley is going to be expensive as its a zone 4. If you want to be close to the centre of london then how about living on the jubliee line somewhere maybe zone 2 or 3. Its more convenient if you want to get to zone 1 quickly.
Personally i live in zone 4 on the otherside of london so i can say that it can be expensive if you want to go from zone 4 to zone 1 on the tube map.
In contrast though I have friends who live in baker street or kings cross and make it into uni on time. It all depends on how much your willing to spend on travel. So i'd say check travel prices if your worried
I hope this helps.
As always ask if you need any more help.
