Definitely not 4 Star. Nothing VIP about this hotel. Room on 7th Flr and have to tell you our room looked very very tired. Carpets worn out, beds hard as rock and walls paper thin and disturbed every night with noises from next door. For 4 days they were fixing the WIFI and no internet. Don't think they have had internet for a while.
Last day noticed bites suspect bed bugs unfortunately.

Stayed here three nights. This is run down and old compared to other options at the same price in better locations. The elevator is downright scary. A large group of us were in town for a major event and this place was bottom of the barrel amongst all of our friends. Our friends all paid about the same and stayed at way better, more modern places than this by the exhibition grounds. We chose this place because it looks close to barrio alto on the expedia map. It's not. In fact, it isn't really close to anything worthwhile.

During our visit, the front desk sent us merrily walking up a steep hill to a closed restaurant, sent us to what turned out to be a known and notoriously slummy (among the locals) part of the beach on overcrowded public transportation, and suggested a nightclub where a friend (also a guest of this hotel) was robbed and beaten. Upon returning from the robbing and beating incident, front desk staff, despite speaking OK English, made no effort to communicate with the Portuguese people we needed to work with (we don't speak Portuguese).

Next beef - we purchased wifi access and were given a card with a username and password. Which the maid stole or threw away while we were out. Upon telling our amigos at the front desk, they grudgingly replaced our access card with a total of three non-working cards. We finally got a username with like 12 minutes of access despite paying for two hours. Losing a few buck is no big deal. Running up and down stairs for twenty minutes trying to figure this out in the process of losing a few bucks was infuriating.

Next- these guys have actual, metal keys for the rooms that they will not let you take out of the hotel. So, you have to ask the wonderful staff to have the key to your room every time you come back. I felt like I was asking my dad for something.

This is a nice hotel. I was so fortunate as to have a room at the back, facing the courtyards and not the road. "Sound Proof Rooms" as mentioned in descriptions (found on other websites) however do not really exist, unless this is available for business meeting rooms only. At several times, I was woken up by people in the next room having a shower or flushing the toilet. In the mornings it was the cleaners making a noise in the hallway.
All in all, it was decent, clean and the staff nice. Room was spacious. There was a kettle and cups for making tea, a telly and a small balcony. All rooms are air-conditioned.
Wireless Internet access was available, but had to be paid for. I found it at €3.00/1hr, €5.00/24hrs and €10.00/3 days fairly expensive, though. I agree with previous reviews that it does not really deserve the 4 star rating as the hotel does need some TLC.

I stayed at the VIP Diplomatico Hotel for three nights at the end of April/beginning of May with my girlfriend.

We had been due to visit Lisbon a couple of weeks before staying at the Residential Alegria, but had to cancel due to volcanic ash. We were unable to rebook at the Residential Alegria as it was full (and we lost the cost of one nights accommodation) but were able to get a double room at the VIP Diplomatico. We paid 52 Euros a night, as part of a promotion they were running.

If you are thinking about staying at the VIP Diplomatico then don’t be fooled by the website, grand name or it’s four star rating. It is a rather dated hotel, with old fashioned and tired furnishings, worn carpets and an old style lift. The bed was also two singles pushed together, which I know causes a problem for some people.

The bedroom had a TV with a number of English channels, limited tea and coffee making facilities, a mini-bar and a safe (which I believe you had to pay extra for). The staff were helpful and spoke good English. We didn’t have breakfast or use the bar, so I can’t comment on that.

It is a good 25 minute walk to the centre of Lisbon (potentially longer depending upon where you were going). It is well placed for buses and the metro, but we found it somewhat inconvenient and too far out for our liking.

We would also laugh as we walked past the very grand looking Sofitel hotel on Avenida da Liberdade as it had the same four star rating as the dated VIP Diplomatico! Whilst there is nothing particularly wrong with the VIP Diplomatico, I don't believe it deserves a four star rating. I would stay there again, but I would try and find somewhere more central first.

I would also suggest that if you are expecting luxury or modern facilities that you look elsewhere. However, if you are able to get a good rate and don’t mind being some way out of the centre then this could be the place for you. Just don’t expect too much.
