BigSur, if you want to contact them email the office through the AW site and they will send you it or if you have any bother PM me and I'll pass it on. Only thing about contacting them is you have to text them. Just send them a text with who you are after or ask who is available, time, incall/outcall, etc and they get right back to you.
The incall is a house off the Saltmarket, in a cul-de-sac. I'm not that keen on it myself as the neighbours must know something is going on but I've not had any problems using it. Although, if I am having an incall I do try and make it when it is quieter, like afternoons or late evenings.
The flat itself isn't up to much but any time I've been there it's been clean enough and fit for purpose.
