Most everything good about St. Ermin's has already been mentioned in other reviews. I'll just reiterate a few that bear repeating. The location is perfect for walking just about everywhere.The landscaping & outside appearance is beautiful. The lobby is stunning. The rooms and public areas were all very clean. The staff is exceptional, especially Gary (concierge). Everyone we encountered were very nice and helpful. The largest choice of items for a continental breakfast I've ever seen. We went on a day trip outside of London and they fixed us "to go" bags and beverages delivered to our room at 6:30am. My only complaint would be the lack of space to put anything in the bathroom. Maybe shelves could have been put under the sink?
Enough said. I would not hesitate to stay at St. Ermin's again or recommend it to others. The hotel made our stay in London that much better.
