I'm looking for a hotel that is near most of the sights in London. Probably near the Picadilly area. I probably don't want to spend more than $150 USD. Thanks.

elsabet: There are hundreds of "hotels in London" threads. You would probably get better results if you: (a) read those threads first; (b) developed a list of hotels that sounded interesting and then asked fodorites some follow-up questions about them; (c) told fodorites when you planned to visit and how many of you are travelling; and (d) gave us some other information that could help people advise you about the right kind of hotel. For example, are you looking for a romantic hotel with your partner, or a room that will sleep mom, dad and two kids, or 4 friends? Are you a "if it's clean, I don't care if it's ugly" person, a "I like the reliability of chain hotels" person, or a "I don't care if I have to climb a ladder to get into bed as long as it's killer-stylish" person? How about noise levels? And why do you want to be near Piccadilly (instead of another area)? The more specific the information you provide, the more useful the answers will be.

In general, hotels in London are often very expensive, and you won't get a lot for US $150 if you make a regular "cancel until 6 pm day of arrival" booking. You can do a lot better if you're willing to take a risk with Priceline or something similar, but you'll have to sacrifice flexibility (e.g. can't cancel reservation or, if you bid for travel, you can't choose the specific hotel or the room type).

Elsabet, I got the Adwych Hilton bidding $120 on Priceline for a four star in Mayfair. I was absolutely delighted. Microwave, coffemaker, and fridge in room. Bottled water delivered daily. Moulton Brown amenities. Huge king bed with exceptionally nice linens. That experience made me a Priceline believer. www.betterbidding.com and www.biddingfortravel.com offer good tips on managing your bids.

Here is what I'm looking for in a hotel:
double room (ensuite bathroom not of importance)
Central Location
-My boyfriend wants to see Big Ben and the Tower of London, I want to see Buckingham Palace
-I'm looking into the Alexander Hotel right now, but any other suggestions would be welcome, I'm mainly looking for a place to sleep for one night we will be there in mid June. Thank you for all of the help.

As I have said before: where you sleep doesn't matter as far as sightseeing is concerned.

The sights you have mentioned are about 5.6 km apart, requiring 1:25 to walk between them. Unless you have weeks and weeks to spend in London, you'll probably use public transit, in which case where you start from each day is moot.

I recommend using buses over the Tube, for a number of reasons. You can specify what modes you want by pressing "more options" at the TfL Journey Planner:

The "begin map" and "end map" will clarify where the bus stops are on each end.
