Myself and 9 friends stayed here for a weekend to celebrate a 30th birthday. The apartment is even more impressive in reality, the photos don't do it justice. It's also located in a really good location, with lots of bars, restaurants and tourist attractions within walking distance. The apartment was bright, clean, spacious and also came with lots of little complimentary extras which were nice. The host was so lovely, and was flexible with both check in, and check out. We had never been to Lisbon before and he was full of helpful advice and tips on where to go, what to do etc.
The only major downsides to the apartment were that the electricity cut out every few minutes in the evening time. This could be fixed by simply switching it back on at the switchboard, but nonetheless, it was extremely irritating! Also, the hot water ran out after three of four showers which is not ideal when 10 people are trying to get ready! Also the mattresses were quite uncomfortable, bit they did the job ok.
