Hi there,
first, sorry for being that late in doing a rating ...
We spent just two days/nights at Karmen & Tom's studio, but we enjoyed the stay very much.
The location / accomodation is well equipped with all the things one needs and even with an internet access (which we didn't use though) and has a very practical separate entrance. A perfect & quiet place for exploring London with a tube station nearby (5 min walk) & Heathrow Airport just a 20 minute drive away.
Karmen & Tom gave us a warm welcome & were very friendly & helpful hosts and made numerous suggestions about how to get to special places or where to find delicious food (ask for the persian restaurant & take-away - you won't regret it, they serve REALLY delicious meals - YUMMY). Conversation was smooth, easy & enjoyable. Breakfast was wholesame & good.
All in all: a great place to stay if you want to explore London or the southwest of the UK. We would book again without hesitation. Recommended!
