It's a bit out of centre but very easy to find with the nearby metro's/subways. We would suggest going upstairs right away out of the station and walking under the building instead of what g-maps say, it would save you some metres.
The place is small but has everything you need to visit lisbon for a few days. The china was limited and not so clean.
The owners leave groceries from last visitors behind so you can find some basic stuff in the cabins. Communication was very fast and on spot.
We had a great time.
