We (dad and I) turned up unannounced, we were advised to by mums CPN, we were Lso told that if we liked a home to go back again, again unannounced but at a completely different time. A home that welcomed you no matter what the time and what was going on was a good one. A home that told you to come back with an appointment was one that wanted to make sure you only saw what you wanted them to see. This was her viewpoint not ours!!! I did ring one home and they did say just turn up, take us as you find us.
The NH that mum is in had a place that had just become available, the SW said pop in, the manager won't mind he's a lovely chap. What failed to be mentioned was 'just' become available actually meant that the poor lady had just passed away! She was still in her bed, the doctor hasn't been out and we walked into the home Infront, literally of her family.
We did say we would go back another time but the manager said no, he couldn't show is round upstairs or the room (obviously) but then your downstairs was exactly the same and he showed us round and in a room equivalent to the one that would become available to mum. We apologised profusely, said he only needed to take 5 minutes but no, we had a cuppa and were there about 30mins. Even though someone had just passed away he gave us the time of day and didn't rush us.
Mums been in her NH a year this month, it's still absolutely lovely.
For me I'd just turn up, providing its not 30 miles away. The ones we saw were literally 5 mins down the road from either dad or myself. We've been exceptionally lucky.
Good luck with your search, I hope you find a nice home.
