Very good hotel, fabulous beds and excellent breakfast buffet. Not very close to the city centre but you can get here easily in a cab (and it's relatively cheap too). Overall a great stay.

Great hotel, excellent standard. Great to have a pool in a city hotel - a real bonus.
Downsides - a good 10 minute walk to nearest tube which is uphill on the return journey. Then a 10 minute tube ride to the centre of Lisbon. Surrounded by busy dual carraigeways. We stayed for 5 days last week and had planned three days around the city and two at the pool. Unfortunately the weather was cold and cloudy so the pool was out. We had a free 7 day 'Colinas' travel card with our booking which entitled us to free tube and bus travel. This was great but the distance to the tube makes the hotel location tiring for daily travel over anything over a coupie of days. Also only a few basic bars nearby - need to travel into Lisbon - would be nice to have been able to walk to good bars and restaurants.
Overall great hotel (although drinks and meals pricey) but pool only a bonus if you have the weather.
Go in the summer and make the most of the pool. Probably best avoided out of season.
Great helpfull friendly staff as well.

I attended a conference in Lisbon and stayed at the Marriott. It was great stay, the room I was in had a gorgeous view. They provide complimentary water in each of the rooms, it was very clean. I was able to use the internet and found all the amenities to be above average. The staff was very friendly and the room service was great! It is located near the heart of downtown Lisbon.
