We have rated Jan's place as "great" because 1) Jan was flexible in letting us check in earlier and check out later, 2) Jan promptly replied to all messages/requests, 3) the apartment was lovely and matched the photos exactly, 4) the shower room was excellent, 5) Jan added some thoughtful touches like including a variety of tea bags (we are big tea drinkers), fresh fruit and basic food items like oil and sauces, 6) the apartment is in a great location within easy walking distance to the Avalon shops and the beach, 7) the big TV had Netflix and 8) the beds were comfortable. Jan is a nice woman.
A minor point is that the internet whilst not super slow is also not super fast (we couldn't do a webcam conversation easily) and the Wifi signal is weak in certain areas of the apartment.
