My fourth stay here and I absolutely loved it, nothing beats the location nor the value for money and nice attentions + warm welcome of the staff! Looking forward to my next trip to what has now become my Mayfair home. Highly recommended once again. A "sans faute" as we say in French;-)

We often go to London for the Christmas holidays and wanted an apt that would be centrally located in the best of London's neighborhood. 9 Hertford Street, was highly recommended by "London Suites", the travel agency we used, read the reviews and booked it for one week, December 24-31. What I thought would be a a safe and great place... More

Had a fantastic stay, great location for all the shops in central london and the apartment was really massive. Only downside was that the person next door played their music really loud all the time and there was a bit of traffic noise - so just ask for an apartment to the back of the building and not on the...

These well priced, spacious, quiet and very comfortable apartments located in exclusive Mayfair are simply wonderful.

We were able to check in to... More

Back at 9 Hartford street, it was such a pleasure to be back in these familiar grounds once again, my third time here and I love it! As soon as you get in, a warm welcome and a feeling of calm and warmth is the first thing that grabs you. Huge flat, splotless, comfy bed and the staff could not... More

I traveled on business and enjoyed the quiet and spacious flat where I held a couple of meetings. The team was very charming and helpful. The concierge organized taxi transfer, theatre tickets and was very helpful. 5 minutes walk from Green Park tube station/ Hyde Park...

I couldn't recommend this place enough! I booked a week end away from home for our wedding anniversary. The suite was very spacious, quiet, and the manager had left a card and small present to congratulate us. The bedroom was huge with a massive and super comfy bed...the living room was classy and enormous. There were two big tvs- one... More
