What a lovely experience. Donna's place is 5 minutes walk from a big, well connected railway station with regular express services to London (Charing Cross & Victoria) that accept the Oyster card. Donna loaned me an Oystercard for my time there which I topped up as I used it.
The bedroom is clean, comfortable and cosy. The ensuite is a Godsend.
I had access to tea, coffee and refreshments including breakfast.
Donna is an interesting host and you should take 10 minutes to chat about anything, it will be worth it.
