The apartment is in a really poor state: dirty walls and furniture, a photo frame broken and lying on the floor, damaged shower, some furniture swollen with moisture.
I've reported the issues immediately, but for 5 weeks I didn't even get proper acknowledgement that it was an issue nor received an apology. There were some people coming to see the state of the apartment on a couple of occasions, apparently wrt an insurance claim, but it didn't feel that the place was meant to be fixed up ahead of the next guests arriving.
When I mentioned the issues to a person met in Lisbon they unprompted have mentioned the name GuestReady. I suppose that means the company has a reputation in the city for poor quality.
Apartment is also located next to bars and clubs and the nearby streets reverberate the sounds. I usually have a good sleep but needed earplugs not to be waken up by party goers at 3-4am on the weekends.
The kitchen in the apartment is also poorly equipped and there is no cupboard space in case in case you wanted to cook, etc
The positives: really close to most of places in Lisbon you will want to go to, the armchair from the photos is amazing, and good fiber internet. There is a kettle and dishwasher.
I suppose the place is good if you come for a short stay to party and don't mind the dirt.
