We stayed one night at Katie and Simon's. The house is very beautiful and the area is really nice. The hosts have written up a nice welcome guide with tips around the neighborhood and beyond.
The room is just as described: the only downside is that since the room next door is also for rent on Airbnb, if you have noisy neighbours you may end up getting little sleep (as we did).
Breakfast was quite minimal -- bowl of cereals.
Simon and Katie were really kind and let us keep our luggage at their place beyond checkout time -- we picked it up right before going to the station.
