Excellent - a very relaxing place with a lot of charm. I only stayed two nights, but I'd like to come back for longer. Irma was very welcoming, and it's clear she is an artist with taste. I also met her son, who too is a very pleasant person.
The house is quiet, in a quiet side-street. There many interesting artworks and old pictures, with some well-chosen older furniture. This is not IKEA!
The bedroom is a good-sized room, with a useful desk, plus a lot of clothes storage space. The bed was very comfortable, with a good quality duvet (I slept well). The bathroom is modern and well fitted. The kitchen has the usual appliances, with a table and chairs, and a door down to the back garden which must be very pleasant in summer.
In the area, recommend The Shirker's Rest micropub for beer, and Chinwag for coffee (both opposite Goldsmith's). And there are many good bus and train connections nearby.
Strongly recommended. I definitely want to come again.
