Rented flat - no children?

It will mean no children living there on a permanent basis,other tenants may not want the noise of babies etc during the night,I shouldn't think looking after your DGC during the daytime would make a difference but just check with the agent and get it OK'd in writing for your peace of mind.

It will mean to children living there, so I suppose it depends how often your DGS visits. Once a week you'll probably be ok, but daily could be construed as living there. The agent should know - and it is (hopefully) short term.

You should ask the agent or owner! Maybe they mean that children aren't allowed to rent the flat.
