Well the friend that had expressed interest has decided it is too far to travel so I think.im gonna put the idea on ice for now. I have a long term tenant I can put in the flat which is probably a better option..but he is a friend so I could probably sublet the place for a week and have him stay with me. If I have any other friends who want to try it as a tour. But I'm not going to advertise. Just people I know and feel I can trust.
