I stayed at Katrina's place for almost 2 weeks, and had a smooth experience overall.
Katrina is responsive and clear in communication, so I gained a good understanding of the household and made arrangements for check-in beforehand. During the stay, it was easy to reach her, and she shared directions and recommendations around the neighbourhood.
Some facilities were faulty when I checked in, i.e. window blind adjustor, light, door could not be locked from outside, but Katrina was prompt in getting them fixed.
Kitchen and bathroom were shared, which were not that clean, but it for sure depends on the cleanliness of other guests. The room itself was clean.
Location wise, it was located in a quiet and safe area, 20 min walk from the closest tube station, supermarkets were ~5 min walk away, so still convenient.
I could cook and use the washing machine, so it's good for longer stays. Overall it was good value for money.
