So many choices in London, but we ended up at JW Grosvenor mainly because of the excellent reviews of the Club Lounge. We took the no step Elizabeth Line directly from LHR for about 15 gbp each to Bond St station. It's a short walk or cab ride to the hotel. Location is great on the edge of Hyde Park, we walked everywhere ! Check In was smooth, but no Titanium room upgrade, as they apologized and said they were sold out. We booked 5 night stay on points (287K) so it was a small tiny tiny Superior Room on the 1st floor but available for an early check in. The space between the dresser and bed was no more than 12 inches and my bf hit his leg on the dresser knob. We found a bottle of champagne waiting for us in our room, which was nice. Attentive service. The best part of our stay was the wonderful staff in the Club Lounge and the food offerings. Breakfast was excellent with typical eggs, sausage, bacon, etc, artisan breads, fruit, pastries, kale and other juices, cereal, yogurt,meat, cheese, smoked salmon. Evening offerings was a whole dinner with different theme every night. Hot entree and sides , 2 salads, breads, cheese, crudite, dip, drinks. We really enjoyed it and it was high quality food and plenty of beer for bf ! Afternoon pastries are sconces, cakes, cookies. We are normally out and miss this, so we asked our friendly staff to save us a piece of cake. To our surprise they presented us with an iconic JW Cheesecake normally 30 gbp. The lounge was never overcrowded and we could always find a seat at a table for our meal. The Club Lounge was delightful and definitely a good reason to stay at JW Grosvenor. I am disappointed we didn't get a room upgrade but totally understand.
