We recently stayed in Smugglers Neuk and had a lovely break for a few days. Parking near the accommodation wasn't a problem. We found a spot and stayed put using public transport to other villages to eat so my husband could have a drink with dinner.
There was everything we needed apart from one vital item - a teapot as we're avid tea drinkers! :-) Seriously though, it was very well furnished and equipped. I have health conditions which make my joints ache a lot and I can verify the bed here is ultra-comfortable. Towels were plentiful and fluffy robes supplied too.
We had a lovely trip to the Isle of May on the boat (not the fast rib) and I'd recommend pre-booking as we did in busier months as it sold out. Our Heritage Scotland cards got good use in St Andrews for the castle and cathedral. There's a lot to see in this area and Cellardyke, Smuggles Neuk was a perfect base, thank you.
