I stayed at Herme's for 4 months, I felt like at home.
Herme was very welcoming, she was very helpful for any enquiry I had it was lovely talking to her even though she works a lot. She always made sure I had everything I needed and was very respectful of my privacy.
The house was always clean. The room was very comfortable (loved the bed !!) and the sun shines through the windows the whole afternoon.
6-10 minutes by foot from Ruislip Station (Picadilly and Metropolitan lines), 6-8 minutes by foot from Waitrose.
I would definitely stay at Herme's again !
