Appaling. After having enoureous problems moving in the flat due to Haines inefficiency I've faced several problems with the flat that were never resolved.
I had a flood, in the property during a saturday night, nobody at Haines answers the out-of hours phone and their plumber will not come out because not sure who pays the bills and, he also can't contact the agency.
I have alerted the agency for this problem several times since the summer and nothing has been done. I had no reply to emails and no letters.
Avoid them... they are terrible.
