We visited the hotel during the May Bank holiday weekend which was a staycation for us before we headed off to Four Seasons Hampshire. Our junior conservatory room was quite small but fortunately we had a massive balcony to enjoy some private outdoor space. Spa and Gym were also tiny and a bit crowded. Therefore we spent most of the time at Hyder Park (playground + boating on the Serpentine lake) and then walked around Mayfair and Marylebone. We dined at Pavyllon and tried two different 6-course tasting menus: we really enjoyed the mains (lamb cutlet and roasted duck magret) but felt the chef had tried too hard on other dishes. Also the restaurant completely missed our 5th course and served us the last course instead - I had to remind them that we only had 5 not 6 courses which was a bit shocking in a michelin-starred restaurant... On the flip side, the front desk (Reka), concierge (Lea) and doorman (Juan & Victor) were very helpful and welcoming. Mr Andrea and his team were extremely accommodating to my requests - they organised a movie night with complimentary popcorns and sweets for my little one and my wife while I was doing some work in one of the private function rooms (free of charge). All in all, Park Lane is a great hotel in an envious location close to beautiful parks and grounds though with limited in-door facilities.
