We booked this hotel through Priceline for $80 a night, which means we paid for the room in advance. But when we arrived for check-in at around 8 p.m. (check-in time is 2 p.m.), the assistant manager informed us that our room had been given away to "a group of guests who decided to prolong their stay." What kind of policy is that? We had paid for our room in advance, and they gave it away to someone who didn't even have reservations ahead of time and simply decided to stay on! The assistant manager then paid for a cab to take us to a sister hotel in a completely different neighborhood -- not at all the neighborhood I requested when I was using Priceline. To make matters worse, she was condescending and dismissive and lacked any sort of empathy whatsoever. Beware if you're traveling on a budget or are a Priceline customer; apparently management at this hotel thinks it can just jerk around those who aren't paying full-price.

My daughter and I went to London on a four day vacation whirlwind trip--booked a package with air and hotel. We stayed at the Millenium Gloucester. Could not have been more pleased. Elegant lobby, attentive friendly staff, clean room, large bathroom, lots of hot water, small desk/writing area, small walk-in closet/dressing room. All of this pales in significance, however, when looking at LOCATION. It is literally 20 steps from the Gloucester Station stop on the Picadilly line. (That is within the first fare zone. You can easily get ANYPLACE you might want to go in London within minutes, and get to and from Heathrow in well under an hour, with no changes or hassles. The neighborhood and tube station are safe at any time day or night. There are a couple of convenience food places open 24 hours, so if you want to use the small refrigerator in the room for snacks it is easy. LOCATION plus elegance. Wow.

My girlfriend and I stayed here for two nights this week. We got a great 'anonymous hotel' deal through lastminute.com

The hotel is very attractive and clean. Our room was on the 4th floor. Everything was clean, and the room was moderately spacious, enough for the two of us. We had a nice daybed in addition to the bed. The bathroom was very nice, and it had a massive bathtub large enough for my girlfriend and myself, so neither of us had to wait after a long day walking around London.

The lifts were frustratingly slow. I feel like most of our time there was spent waiting for an elevator to arrive.

The neighborhood (South Kensington) was very nice, and the hotel was only 30 seconds from the Gloucester Road tube stop; the Piccadilly line is especially convenient for sightseeing.

The hotel meals looked expensive, so we got a lot of our breakfasts and snacks at the Tesco convenience store across the street. We ate very well there, a whole bag of donuts is only 50p (about $.99), compared to an expensive English Breakfast.

The hotel is very nice though it is usually expensive, so watch for great discounts.

We stayed in a very nicely appointed twin room. When we asked for a free upgrade we found that the previous room was better! The beds are quite comfy, the water pressure was great, and we had complimenatry coffee/tea daily in the room. Often we'd shop at Tesco across the way and buy heavenly "flapjacks" and the best yogurt we've ever had (passionfruit-mango-papaya or a Muller cherry or vanilla w/crunchies) and storing it in the fidge. Just make sure you are not charged accidently as there are motion sensors in the fridges. The tube (across the street) connects 3 convient lines. Be smart and buy a travelcard on RailEurope.com. The was a free ATM next to tube at the Bureau de Change. We loved eating at the various food courts and local sandwhich chains. The city is affordable if you look around a bit. All museums are free and fabulous. You will love coming "home" to a nice hotel tucked away in a lovely and quiet area. Also, I suggest using internet services in food chains (Subway on Bond St. has a huge internet cafe that's very cheap). London (one of the greatest cities) is what you are there for anyway-not a hotel room; though fortunately we were happy and likely to repeat our stay there.
