We stayed one night, seeking to be near the train station. The hotel is easy to find, easy to walk to with luggage. There is no ramp, so you need to carry bags up the stairs to enter. We booked a family room. The child bed was a roll-out cot and not very comfortable. The room had air conditioning, though, which was a huge plus in the London heat. The bathroom was super clean. Cafes are nearby and the location is great. I recommend the hotel to travelers who want to be near Euston or St. Pancras, with the caveat that if your child is particular about sleeping in a non-portable bed, you may want to consider that.
Good: Room is quiet, metro is 6 min away, Eurostar station is just 12 min away, bed is comfortable, housekeeping is good, service at concierge is good, we borrowed umbrella from them, room is clean
Bad: Cannot think of any
Good location. Tasty breakfast. Very helpful staff, arranged my check in as early as 10 o'clock in the morning. Quick check in and out procedure took only about 5 min. The room is clean and well equiped although a little bit small.
