I stayed at Marta & Rui's apartment in Lisbon for 3 Weeks in December. It's a beautiful place and located right next door to the LX Factory and the bars and shops within, and directly under the bridge.
The apartment was clean and has a large double bed in bedroom and a small child’s bed in Living Room and is well equipped for a few days in Lisbon. As I was staying for 3 weeks there were some things lacking, such as TV, laundry, better cooking facilities etc but the Internet was good for work and there is a laundrette very close and a choice of restaurants at LX Factory. In fact, it backs on to the LX Factory and you can hear the music from the LX factory in evening. I wasn't bothered by noise during my stay (although the Neighbours dog can go off at times).
There are a good Supermarkets near-by and transport stops close by. It's near to Belem and about 15 / 20 mins by Bus from the Time-Out Market, Cause do Sodre etc.
I had no problems during my stay and would be happy to return
