The host Julie was extremely good about responding to messages and queries. She even sent us some photos of how to access the property, which we appreciated. It is in a courtyard, set back from a quiet street. The house is indeed about 10 minutes walk from the cathedral: from and to the station took us longer, but within 20 minutes.
The house is comfortable, the wifi is excellent, and the shower works well.
There are a few points:
the staircase may be tricky for some people to negotiate - a handrail seems to have been added on the wall side since the vrbo pictures were taken, but it might be easier if this went all the way down;
the hob is in the corner, and the controls are along the far wall, which makes it a bit awkward to use.
But overall the little house was very nice, very good value, and we enjoyed our stay.
Thank you!
