Oak Cottage is in Robeston West, which is near Haverfordwest. It's part of a row of three cottages on one level, so there are no stairs to worry about. It's in the grounds of the main house, but you get your own patio and garden area.
It sleeps four, two bedrooms, one bathroom. It's got a 4 Star rating. The kitchen is a galley style, so it's long rather than wide. Both bedrooms are decent sized.
There's a shared games room on site with a pool table and table tennis. There's also an outdoor climbing frame for kids. You get your own hot tub on the patio. The tennis court and small gym are available too.
The coast is about a ten minute drive. Little Haven and Broad Haven are the closest beaches. Good for walking and you can get food at the pub in Little Haven. The Pembrokeshire Coast Path is right there.
Further afield, Tenby is about 40 minutes. Places like Folly Farm and Heatherton are within that sort of drive too. For boat trips to islands like Skomer, you'd go to St Martins Haven.
Facilities: it's all on one level, which is good for wheelchair access. There's a cot and highchair if needed. Bedding and towels are included. WiFi. One well-behaved dog is allowed. Parking is right outside.
