My husband and I would highly recommend Urban Cottage. We stayed for 3 weeks with 2 young children while visiting family in the area (we live overseas).
We had no problems during our stay but if we had had, I'm certain the host would have been quick to respond and remedy any issues based on our communications both before and during our stay. We couldn't speak more highly of the host.
The cottage is well equipped with most things you might need (eg hair dryer, laundry detergent, well equipped kitchen etc) plus some thoughtful extras which we appreciated. One of the best features of the cottage is it's proximity to public transport links and conveniences (eg supermarket, coffee shop) while also being very quiet and private since it's back away from the main road behind a gate.
The only things I can think of as "suggestions for improvement" are minor and would be 1) a second key to make coming and going a bit easier (my husband and I weren't always together so had to make sure whoever had the key that day was going to be back in time to let the other person in which wasn't always convenient) and 2) maybe a dust buster type vacuum. There's a broom that we used but it struggled to do the job with two little kids dropping crumbs and traipsing in dirt every day. But then I understand that most people who come aren't bringing young children nor staying for as long as us and therefore wouldn't need to vacuum.
We thought Urban Cottage was good value for money and we would certainly stay there again.
