PenguinsandtheTantrumofDoom - I wouldn't have taken those comments as complaints, as such.
Estate Agents can be very pushy for some sort of feedback about the house. 'It's not what I was looking for' is RARELY good enough for them. They want details, and lots of them, so as a viewer you just give them something that gets them off your back.
So yes, the quirky layout would be one that would be mentioned, not enough bedrooms, again, a definite one.
They do that so they can 'supposedly' show you houses that meet what you are looking for. In reality it's just a box checking process so they can show that they're doing their job.
Oh and the appointments to view a house - I've had estate agents line up several houses for me to look at, none of which met the criteria I had left them such as number of bedrooms, outside space, etc. So yes, my feedback WAS not enough bedrooms, lack of outside space. He had arranged the viewings without telling me what they were for, simply because I wanted to see one particular house.
It got to the point where I would ask to see the brochures right at the beginning, look through them and say 'yes, no, no, yes' to seeing them. What is the point of seeing them if they don't meet the minimum requirements?! I felt sorry for the sellers, but I wasn't going to waste my time viewing these houses just because the agent was an idiot.
