Have just tried to arrange a viewing only to be told that the only viewings are in the evenings or at weekends. As I have a 3yo and a 7mo, evenings are out which just leaves Saturdays. Not an easy day for us atm, for various reasons.
I would just think that in the current climate, why not let the agent have a set of keys so you could get all possible viewings?
Ah well, will have to go another time...!
