We had a great time at Cláudia's place. It was very neat and tidy and had everything you need. The bed and mattress were also very decent (I was a bit worried about that, since people often tell about small/uncomfortable beds in Portugal). Overall we highly recommend the place to anyone looking for a place to stay in Lisbon. One word of warning: due to thin walls and gaps underneath the door, it can be a bit noisy. So if you have trouble sleeping with some noise, it's better to bring some earplugs.
