Fernandes' description of his place is mostly accurate - the apartment looks like the pictures, and is well located. We had a nice stay in Lisbon but there were a few omissions in his description that may have swayed us away from booking.
The entire building was demolished a door or two down the block and is being rebuilt, meaning there is a lot of construction noise during the day. Although Fernandes did provide us with earplugs, and it is no fault of his own that there is construction nearby, it did impact our stay. Once the construction is finished, staying at this apartment will be much more enjoyable!
The description lists an air conditioner in the reviews, which was a requirement for us when we were looking at places to stay. It does exist, but it is a wheeled, stand-up air conditioner with a large circular hose that needs to be placed through a window as a vent to the outdoors. The windows are large, shutter-style windows. So, if you want to use the air conditioner, you must keep a massive shutter-style window wide open. The street is very noisy, from crowd, construction noise, and trash collectors all the way through the night. Thus, we were forced to choose between roasting from the heat in a quiet apartment or being constantly awoken by loud noises. If it weren't a hot summer month, this would not have been an issue for us -- but in August, this was a deal breaker!
Finally, there were no toiletries (shampoo, conditioner, body wash/soap) other than hand soap. This was not a big deal for us as we had brought our own, but worth a mention.
Overall, the apartment is good value, and in a good location. The check-in process was seamless and we did not have any issues with the host. However, the construction and the lack of AC in the summer were absolute deal breakers for us.
