Roy is a great host. The location is perfect, and you can reach the city centre (Royal Mile) in a 20min walk. Pippa is a lovely cat, but as already mentioned, you need to be ok with a cat in the house (odour, cat hair...) The room is spacious and has all you need. You can use the kitchen and the lounge.
However, I cancelled my reservation a day after the arrival since I think the mould found in the bathroom and the bedroom is a severe health issue. Since more than 120 people left positive comments, I leave it to you to decide if that concerns you.
