I had the room 4537 ,nice and small , nice bathroom !
however except the reception , people is not very nice , service in room is extremely slow , to the point that the breakfeast was so long that I went downstair to take it ;
Don't want to talk about the restaurant , I didn't have a reservation , I asked for but the woman was so rude that I didn't went ,you can avoid to go there , it's so many nice restaurant in London with nice people that going to treat well , or at least to be polite !
I will not go back in this hotel , the price is not justify .
for the same price you can go the Dorchester , it's 30 sec walk .

We recently stayed at this hotel for the weekend. It is fabulous! We only had a standard room and i have to say its as good as most other hotels super deluxe rooms. The hotel was the former playboy club and has been refurbished to a fusion of art deco and contemporary style.
This hotel only has 45 rooms, a restaurant, a bar and foyer. So it almost has a boutique feel.
The strength of this property though is the staff. We were greeted at the door by name and then at reception. Our host Ivana was a delight showing us to our room and informing us of how all the gadgets work. She arranged for our lunch and confirmed our dinner reservation. Ivana knew it was my birthday the next day and arrived in the evening with a plate of goodies with happy birthday dusted in chocolate on the plate. I had a similar thing at breakfast that day with a candle.
The restaurant staff led by tariq were excellent also.
I felt that everyone from the doorman upwards tried to make our stay perfect, and they did!
This hotel belongs to the same group as the Dorchester, and as its across the little road its easy to use all of that hotels facilities if you need to. So if you are coming to london do not hesitate to stay here. Its located next to all the top hotels on park lane so location is also perfect. Absolutely first class.

we spent 5 days and 4 nights in 45 park lane last week. business + pleasure. the hotel is great fun. although it is brand new, which means you have almost every gadget possible in the room, its decor is warm and inviting. what is more inviting is the team, who go out of their way to please you and to provide every request 24/7.
add to this a great location, which facilitates an early jog in the park and a "green" view from your room and from the breakfast table, and the cut restaurant, which serves great steaks, and you receive a great complete package.
will definitely return.

So my wife and I had an overnight layover in London and I decided since she'd never been to London, might as well splurge, especially since it was the last night of our honeymoon.

So upon arrival, we were pleasantly greeted and escorted to our King room. Well so we thought...they upgraded us to a Park Suite! Wow is all I can say...I don't know what type of person stays in rooms like this on a regular basis (2800 sterling) but I could get used to this! Huge room with two B&O TV's and all the works. We were given a dessert with congrats on it and a bottle of Champagne. Only problem was as soon as we got there, we needed to get dressed ASAP and get over to Alain Duccesse for dinner and the Dorchester next door. On a side note, amazing meal, don't get the filet mignon though...

We got bak to our room around midnight and enjoyed it for the next few hours with a great room service for breakfast on our dinning room table. Loved 45 Park!
