A lovely place. Jessica is a very warm and welcoming host. The summerhouse is located in the garden, so you have your place entirely to yourself! - it's a cosy space with a bed, tea/coffee/kettle, biscuits etc. Very warm (I was there in mid October!). The bed was very comfortable.
I was able to wash / have a shower in Jessica's main house's bathroom. It was quite obvious that Jessica wants to make her guests as comfortable as possible. Prior to my arrival, the communication was excellent, too - instant responses within minutes over an extended period of time.
All in all, if I am in Edinburgh again (not far from the centre), I might see if Jessica has availability again - loved the stay.
