We stayed at this hotel in May as my partner was attending a conference, As I was the one not attending the confrence I found that while this is a very nice hotel, the downside is that it is too far from the centre of the city. It caters more for the business clientel and large tour groups. The upside is that taxis are cheap in Lisbon and it cost about 4 or 5 euro to get into the old town area. The hotel itself is very nice. The rooms are a good size and the staff are helpful and friendly.

I stayed at the Lisbon Marriott Hotel for 5 nights as part of a business trip to Lisbon. Most of my time was spent at the Congress center or at the hotel. This hotel is your standard upper level Marriott property. It has the newer Marriott beds and in room amenities.

The breakfast is worth the 10 Euro surcharge. Internet is fairly fast, although we did experience one outage during our stay that was fixed by the next morning.

This hotel is NOT ideal for exploring Lisbon, it is however a great business hotel while you are in the city. See my other Lisbon reviews for a great leisure hotel in Lisbon.

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.
