Checking in for me was a bit of a nightmare because the owners weren't around & they could hear the tiny bell or me knocking on the door. It took took a long time & 2 phone calls for the owner to know I was there. Once there, the problem was dealt with quickly & efficiently.
Maybe an alternative system such as a louder bell that rings in the main house when someone enters reception would be good.
Also the sign on the window of reception wasn't visible from the outside to there was confusion as to where to go. Another couple asked me where reception was later in the day due to lack of signage.
Basic toilet/shower facilities with no hand soap & didn't see any sign of them being cleaned all weekend. £1 for shower seemed steep plus the coin meters are all together on the wall outside of the individual shower cubicles - so if money runs out you have to leave the shower to put more money in.
A charge of 20p to fill a bowl to wash up is ridiculous too - I've never been on a site that charges you to wash up, especially when there's hot water freely available in the toilets for handwashing.
Lack of electric hook-up for tents was disappointing, especially when the facilities are there but are "only for caravans".
Noise from the road can be a nuisance, especially from motorbikes.
