Description

Sea Gem is a three-story, contemporary house in Castletown, Portland, Dorset.

This lovely abode provides private parking, ground-floor living, and an enclosed garden for a family or group of seven to explore a stunning location, with easy access to Chesil Beach, Dorset AONB, and the Jurassic Coast.

The ground floor has a large kitchen/diner where you may cook at home in the fully equipped kitchen, which has a breakfast bar and an extended table for all seven guests to dine together.

A ground-floor bedroom with a small double bed, storage space, and a wall-mounted Smart TV, as well as access to a Jack-and-Jill shower room, is ideal for grandparents or those with limited mobility.

After a long day, relax in the bright and airy first-floor sitting room, which features a plush sofa, Smart TV, Xbox, and a collection of books and games.

Open the French doors to enter the enclosed, private courtyard, where you may dine al fresco, relax on the sun loungers, or play games on the AstroTurf.

Sea Gem also has an outdoor tap with space to hang wetsuits after those busy beach days.

A double bedroom with Smart TV and the family bathroom, a stylish spot to relax with a bubble bath or hot shower, round off the first floor.

Two further bedrooms, a king-size and a double, are located on the second floor, each with Smart TVs and en-suite shower rooms.

Sea Gem is located on a quiet, residential street in Castletown, close to Portland Castle, Osprey Leisure Centre, and Portland Marina, so you can start your vacation exploring the Isle of Portland.

The coast path is just around the corner from the house, and there is direct access to the sea via a jetty close to the castle.

If you want to take a break from cooking, there's Chesil Chippie, The Cove House Inn, and a variety of cafes to choose from, as well as beautiful walks and cycling along the coast and the Rodwell Trail.

Visit Fancys Farm, Tout Quarry sculpture museum, Portland Bill, and Portland Museum, housed in 17th-century stone cottages, for more family-friendly excursions.

The seaside town of Weymouth, with its bustling harbour, has something for everyone, including swimming and sunbathing at Weymouth Beach, SEA LIFE Centre Weymouth, and RSPB Radipole Lake.

Enjoy Chesil Beach and schedule a boat excursion at the Wild Chesil Centre or stay on land and explore the Jurassic Coast and Dorset's countryside.

Dorchester, the county town, is a short drive away and offers lots of history to discover at the National Trust's Max Gate, the former house of Thomas Hardy, as well as a number of museums and the Kingston Maurward Animal Park and Gardens.

Choose Sea Gem for a wonderful break along Dorset's stunning coast.

What a great holiday we had.

The property itself is brilliant and very well designed from a layout perspective. Would 100% recommend. Fairly close to the Park and Ride 10 min drive, and made it so much cheaper travelling into Weymouth itself with 2 small families.

Sea Gem was an absolute gem, it was very comfortable and clean, we loved the coziness of the place.

Portland holds a special place in our hearts and always will, and now so does Sea Gem, there was a small niggle and that was the pressure of the shower in the master bedroom’s en-suite the water wasn’t very strong neither was the bedroom’s one next door and i love a shower at the end of the day it is something I look forward to, but wasn’t able to experience that here, also the doors in the front room that lead outside, at night there is no privacy from the roadside luckily I had a big blanket that I could put up to make it feel more private, other than that everything else was beautiful, I would definitely stay here again if the shower was more powerful.Thank you for letting us stay in your lovely home.
