By far the worst letting agents I've ever rented from. If you ignore all of the advice you see on here warning you to stay away and you decide to rent from them anyway I would highly recommend that you keep records and evidence of all of your interactions with their staff - take photos, save emails and make a note of the things their agents say to you in person. They are not trustworthy and will try and blame you for the poor state their flats are in. Be persistent and hold them to account - it'll take a lot of work but with time and effort you can force them to do their jobs and to make those essential repairs. Beware of the illegal fees they will try to charge you and refuse to pay them. Don't let them keep your deposit, take the dispute to the independent adjudicator at Safe Deposits Scotland or a tribunal.
