Communication with Linda is good no problem at all. Only one point is that she probably does not live there so if you want some super details about something special she might not know about it but she is helpful and try to finds the answer.
Flat is pretty much the same as on the pictures, it is clean at last we has it clean, the bed is a bit spine-braker, but for few day stay it is alright. A bit annoying can be your neighbours because the flat is on the ground floor and probably some family lives upside and it is quite loud when someone is walking above. For those who can be waked up by a mice it's gonna be a nightmare. But me personally, I do not even recognise it.
Location is perfect really, neighbourhood is very nice and seem traditionally no skyscrapers or modern building, everything historical. Shops are like 10 minutes walking distance same as the bus stop. Travelling in Dublin by bus is total mess. If you want to see as much of Dublin as possible rent a bike or a car or buy a pair of comfortable sneakers.
