From my parents, who stayed at Nicks place:
Very comfortable. Quiet street. Sophisticated but also very welcoming flat.
Nick's place was great. Comfortable in every way. More clarity about breakfast would be helpful for guests, whichever direction it goes. The lockbox was tricky for us but that may well say more about us than the lockbox. The rain spilling off the roof during the night was noisy and might be troublesome for people trying to sleep. Other than that, it was a very quiet day and night.
