My girlfriend and I stayed at Alexandre's place in Lisbon. The place was as described and it served us well. It's not very big but more than enough for two people. The bed was really nice and we slept well, no noise. The apartment inside looks far better than the entrance itself. Well located, 2 minutes from the Intendente metro station so it was really easy to go everywhere. 10-15 minutes to Chiado/Bairro Alto etc. Tram 28 also stops very close by.
Overall we were happy with the stay. Very unpretentious and simple, so if you don't mind that, you should take the place.
