We stayed in the Estuary Lodge last year (Summer 2010), and we absolutely loved it. The room was lovely, parking was very good, the welcome was very friendly and the cooked breakfasts were fabulous, and relatively healthy (all cooked on a hotplate, with eggs as fresh as they can be - chickens on site!).
For an evening meal, there was a fantastic pub a few yards down the road, and you can take a train to other nearby places such as Harlech (you have to wave it down because it is not an automatic stop station). We can recommend Harlech Tandoori for a very nice Indian meal.
The staff at the lodge were also incredibly helpful regarding travel locally around this part of Wales. We let them know where we were planning to go, and they recommended the best road route to take (there are many precarious and steep roads in Wales!).
The other great thing about this Lodge is that you do not have to go up an impossibly steep hill to get to the entrance to the guest house - it is all on the flat.
We would definitely be happy to visit there again.
