Around now, you might be dreaming of the fabulous “staycation” you could take this summer if only you had a lovely, private backyard where you could grill delicious dinners, enjoy the cool splash of a water feature and relax in the garden.

For most city-dwellers, that dream could only be a fantasy, but for the next owners of a stylish Commonwealth Avenue condo, its private fenced-in, 600-square-foot patio area will make them feel like they’re taking a holiday on Nantucket without actually leaving Boston.

The current owner did a beautiful job decorating the home.

“She has great taste,” Cohen says.

Over the past several years, she brought tremendous warmth into decorating the home, using earthy colors on the walls and window treatments and Brazilian cherry flooring on the unit’s main floor to complement the tones of the exposed brick on the fireplaces.

When you step inside the home, you’ll gravitate immediately to the large bow windows that let south-facing light pour in. The open layout of the living room, dining area and kitchen doesn’t waste any space. The ceiling, which is about 10½ feet tall, adds volume to the whole place.

Start your tour of the unit in the kitchen. White cabinets and drawers offer ample storage for all kitchen necessities. You’ll discover additional storage space behind glass doors built into the breakfast bar. The granite countertops shine in soft gold.

Appliances, which include a large side-by-side refrigerator, a gas range for gourmet cooking, a built-in microwave and two Fisher & Paykel dishwasher drawers, are all stainless steel.

Intimate dinners can be served in the cozy dining nook beside the kitchen. A round table works well in the space.

Nearby, the living area is very pretty and the perfect place to entertain guests. There’s room for a good-sized sectional and coffee table in front of an ornamental fireplace with a graceful mosaic on the surround. There is a place on the wall over the mantel to hang your TV.

The master bedroom is a spacious room where you will be delighted to retreat at the end of the day. It rocks a brick fireplace opposite the bed and three oversized bow windows looking out over the patio. You can put up your TV over the fireplace mantel.

Wardrobe storage is no problem here because there’s a custom California closet with room for all your clothes. The ceiling fan creates a breeze whenever you want one.

There is no master bath, per se. The full bathroom on this level is at the other end of the unit so that guests can use it as well as the homeowner. It’s nicely tiled with accents in the color of terra cotta and a step-in shower.

This home is on two floors. Take the stairs down to the garden level where you’ll see a wonderful guest bedroom – currently used as a family room and office. The ceiling is almost 10 feet high here so there is no sense of being in a basement. It’s a large, bright space with bow windows and its own entrance. The engineered hardwood flooring looks exotic and its stain coordinates well with the exposed brick wall.

A spa-like white marble bathroom is one of the highlights of this level. It is chic and modern with a walk-in shower with frameless glass doors. The dark vein running through the marble is gorgeous on every surface, especially on the vanity countertop.

Although the building has laundry facilities, this level of the home has a laundry hookup for your washer and dryer in a large closet to add some extra convenience to your life.

This home is a treasure in a prime location along the Commonwealth Avenue Mall, so you can go across the street to walk your dog anytime. Or you might choose to stroll over to the Charles River, which is only two blocks away.

Rental parking is available for $250 so you’ll be able to hop in the car for your out-of-town commute or a trip to the Cape - if you ever decide to leave home.

However, instead of leaving, you might find yourself tempted to relax out in the fenced-in private yard all summer long. Enjoy the shade provided by the big tree out on the patio, inhale the fragrance of the garden, and experience the sound of the fountain, while your dinner cooks on the grill. It’s the ideal way to enjoy an outdoor room of your own.
