This flat is in a great location! We loved being so central and walkable to shopping, restaurants, theatre, and many of the central London neighborhoods we visited. It has everything needed for a comfy stay and was a great value. The 3 flights of stairs are a good daily exercise for sure. The only time that was a hassle was lugging our suitcases up to the the flat. Other than that, not an issue for us. Unlocking the key the first time around was a challenge. But like most old locks, once you figure out the trick, it’s easy. Basically, turn the first time around fully and then as you begin to turn around again, nudge the door at the same time and it will open. Thanks for a wonderful stay!!
