Stays in Oeiras

I would choose the Palácio dos Arcos for a family that wants a five-star palace with a kids' pool. The refurbished 15th-century palace on the Estoril Coast has an indoor pool, an outdoor pool and a dedicated kids' pool, plus the Satsanga Spa with massages, a hammam and a sauna. Rooms are decorated with Portuguese poetry-inspired themes. The beach is 350 metres away. Guests rate it 8.9 across 737 reviews.

Lagoas Park Hotel is built mainly for business travellers working on the Lagoas Park office campus, so families should know what they are booking. Rooms are modern, with a work desk and a marble bathroom, the gym is open 24 hours and the restaurant serves international dishes. Free parking helps families on a road trip, and Oeiras Marina is about 5 kilometres away. The listing mentions no pool or children's facilities, so I would use it as a quiet overnight stop.

Holiday Inn Express Lisbon-Oeiras is a modern three-star chain hotel less than 3 kilometres from the Quinta da Fonte and Lagoas Park business parks, and 15 kilometres from central Lisbon. Rooms come with a work desk, a flat-screen cable TV and tea and coffee facilities. The Great Room serves a breakfast buffet with local olive oil and fresh bread, and takeaway delivery is available. Guests rate it 8.3 across more than 4,100 reviews.

Hotel Real Oeiras is a four-star hotel with an outdoor pool, a gym and a Turkish bath, 17 kilometres from Lisbon and Cascais via the A5 motorway. Air-conditioned rooms have cable TV, a minibar and free wired internet. The à la carte restaurant serves regional and international dishes for lunch and dinner, and the reception is open 24 hours. Guests rate it 8.2 across more than 2,200 reviews.

B&B Hotel Lisboa Oeiras is a three-star chain hotel with family rooms that have air conditioning, private bathrooms, work desks and minibars. It is 1.7 kilometres from Paço de Arcos beach. Pets are allowed, free Wi-Fi covers the public areas and the front desk is open 24 hours, which suits late arrivals. Guests rate it 8.2 across more than 2,300 reviews. It is a practical, functional base.

I would choose Hilltop Oasis for a family with a car who wants a garden and a pool away from the seafront. The hotel sits on a hillside in Barcarena, inland from Oeiras, with spacious rooms looking over the garden or the hill. There is an outdoor pool with a view, two restaurants, and free private and bicycle parking. Guests rate it 7.6 across 987 reviews.

INATEL Oeiras gives families a seafront base on the Estoril Coast, looking over the mouth of the Tagus estuary toward the Bugio fort. Every room has a private balcony, a seating area and cable TV, so parents get some space once children are asleep. The outdoor lagoon-style pool opens during the bathing season, the beach is about 600 metres away, and private parking is free. Guests rate it 7.3, so I would book it for the setting and the pool, with modest expectations.
