The apartment was really well located in the center, close to beautiful Fado café's and in the middle of small, romantic streets. The apartment is not big, but has everything you need. It's also naturally cool, so no air-con is needed. The fan is enough to keep cool ;). The bed was a bit 'cosy', since it's only 1,20 m wide. We had a great time in Lisbon!
I would definitely advise you to go to Guiseppe's apartment!
