Great hotel—I had a room with a wonderful balcony. It was lovely.
The staff was excellent, very friendly, helpful.
The location is close to the park, which is wonderful. It's also close to Paddington Station, which is a mixed blessing. Very easy for getting around, but a bit stressful to traverse. I ended up using the Lancaster Gate stop on a different line—which is also nearby—more often.
The Pride of Paddington around the corner from the hotel is a fantastic place for breakfast. Delicious.
The only thing I'd say someone should be aware of is that the hotel—and maybe others in London—get skittish when it comes to bringing guests to your room. It happened to me and I saw it happen to someone else. One guest is allowed; more than one is not.
It was a little weird to have the night attendant react with concern about having a friend over. But again, that may be a city policy. And otherwise the staff could not have better.
I would definitely stay here again. In fact I hope to.
