I believe Altis Hotel use to be a 5 star hotel but not anymore.
For example: the staff at the front desk is not enough, so they are always busy so when they came to help you, because they have other people to help at the same time, they get confused. They mess up with our check in, with our laundry and with our internet. Everything was solved, but we had to call front desk or go there and explain what was happening.
One thing that caught my attention was the gym hours. Usually we can use our key room and have access to the gym, and usually in many 5 stars hotels it is open 24h. But not here. Again, I think because there isn't enough employees they had really restricted hours.
Although they have recently renovated the hotel, it wasn't done throughout the building. So when you walk around you can notice the contrast.
Its not a bad hotel, but it's not at all a 5 star either.

Great location at a great price. Just a couple of minutes walk to Liberty Avenue. Short walk to hop on hop off buses and about a 15 min walk to the river. A little larger and nice than the Aveinda which is located right on Liberty Ave. We stayed here two nights and felt safe during the day and night when we walked around. Great showers in the room, this is important to us and we were not disappointed. Taxi costs to the airport should be around 20 euros, make sure the taxi is not high flagging it.

I was in Lisbon on business and the hotel had been chosen by the company. Since it was for a week, my wife accompanied me. Arriving at the hotel the entrance is quite impressive and walking around the area, the location is ok.

We checked into the room and this was in the newly refurbished area and was quite nice. We had a few issues with the internet, which was a problem for this being a business trip; the wifi does not work in the rooms and, in our room, the wired connection at the desk didn't work. This couldn't be fixed so using the internet could only be achieved by working sat on the bed, not ideal.

The next morning we went down for breakfast to possibly the worst buffet I've ever experienced in a room that wouldn’t have looked out of place in a badly run old peoples' home. There was nothing that either my wife and I would liek to eat so we took to going to the local cafes for breakfast. Since breakfast was included in the price of the rooms, and a €25 per day surcharge was levied for my wife which we were not allowed to decline, the quality of the breakfast was wholly unacceptable. On the basis of this one thing I would recommend that this hotel be avoided and it seems so unnecessary as the pastries supplied during our meetings and the lunches were really good.

Other irritations were the permanently failing door keys which always required reprogramming, irrespective if they'd been near your mobile phone or not. We took to always having it reprogrammed as we entered the hotel so as to not have to come back down from the room in the terminally slow lifts. Additionally the gym was a joke. One running machine and one rower and some free weights is not a gym - for a city centre 5 star hotel it was ridiculous

However, it was the quality of the front desk staff, one individual in particular, which make this one of my all-time 'avoid at all costs' hotels. We asked one evening if a reservation could be made at a new restaurant, Taberna 1300 in Lx Factory. At first attempt the restaurant couldn't be found. After we found it ourselves on the internet, taking an outrageously long 30 seconds in google, we went back to the desk with the telephone number. The individual called the restaurant, came back to us and stated there was no answer and then walked off, no offer to follow up, no assistance nothing. We rang the restaurant ourselves and made a reservation (it was brilliant - I do recommend it).

On a number of other occasions discussions with the front desk staff just left us with the impression that we were an encumbrance not customers. A number of my colleagues experienced similar unhelpful service at the desk.

5 stars is about service and attending to your customers’ needs - something that was too difficult here. The hotel does not warrant the rating and the rooms, though nice, don't make the hotel. If I stay at a Ritz Carlton I have immaculate service, that's what 5 stars is - this hotel has a lot to learn.

Very good welcome. The bedroom was beautifull and very clean (we booked a deluxe bedroom). The hotel was quiet and the breakfirst was very good too. We didn't try the swimming pool or the gym room. For the next time :)
