We spent a week at Sea View with our kids aged 1 and 4. We have a fair amount of experience with self-catering accommodation across the UK and this was one of the really, really good ones.
The flat has been very recently renovated to an exceptionally high standard. The decor is neutral and smart and everything is very good quality. The bathrooms are lovely and the shower was excellent. The kitchen is well-equipped and works well, with beautiful mountain views from the window. The lounge area was very comfortable and such incredible changing views out to the sea and Anglesey, we just loved it. All beds were comfortable - not always the case in holiday accommodation!! There was a box of toys which was much appreciated by the kids, and a good selection of DVDs - oh and TV was superb, and there was even Wifi, which made a huge difference when planning trips!
I really don't have anything bad to say about this place, it was just perfect. Gary and Myriam had left useful information about how everything worked and activities etc. and also answered the queries I had once we arrived very promptly.
In terms of visits, the location is just ideal. We visited Lllandudno for a trip down the pier and also a ride on both cable car and tram up to the Great Orme. We went to the excellent RSPB reserve at Conwy. We saw Caernarfon Castle and also Penrhyn. The railway at Lllanberis and railway centre at Betws-y-coed. The pier at Bangor. The Bodnant Welsh Food Centre was lovely for a coffee and scone, as well as stocking up on lovely local produce. And of course we spent a few afternoons just kicking about the beach out front.
The village is a bit further up the hill really - maybe ten minutes walk, but we just nipped up in the car mostly. There is a really good Coop, about to be extended into a new store, as well as a few other shops including a PO, cash point and a decent fish & chip shop and really good Indian takeaway. There was also a pharmacy in the nearby medical centre which is always helpful with kids...!
All in all, I can't recommend this accommodation highly enough - great location, great flat, great holiday. If you haven't been to this corner of the world, go now, and stay here.
