The apartment has a optimal location as everything is reachable by foot (supermarket, restaurants, some parks) but if you are in Lisbon i recommend to use Uber as it is very cheap to go from one place to another.
The apartment is in a quiet neighbourhood - the only noise you hear is from the airplanes BUT you have this almost everyhwere in Lisbon so i had not a problem with it at all.
The apartment has everything you need and the decoration was quite nice.
The bed is very comfy (at least for me 1,85m 83kg). The shower pressure was also good as i read in one review that it had problems - probably fixed worked fine.
In the apartment a paper with supermarkets, restaurants etc is available from the host.
Check in was fine as well as the check out.
I had a nice 2 months in the apartment and can fully recommend it to other people.
Thank you Augusto/Cristina
