Family of 3 (two seniors) stayed at the Nelson's 2nd floor apartment for a week. The space appeared to be relatively small for three adults - would be excellent for two for sure, while neat and clean. Do not expect any frills but rest assured that you will find everything you need for your stay (kitchen and accessories for cooking, laundry, media/internet, etc, - everything we could need was available).
The advantage of this apartment is definitely its location - in the heart of the city, plenty to see, good food, shopping, a big party at night next door at the funicular. If you are travelling light, it is very close walking distance to public transportation to/from the airport and for day trips out of Lisbon. However if arriving with luggage, make sure your taxi takes you to the exact placed advised by Nelson or you will be climbing streets and steep hills. Anyway, don't be disappointed - steep staircases and paving stones are Lisbon's particularity and unique fabric of the city!
Upon our departure Nelson kindly arranged taxi for us and it was quite convenient. Thank you Nelson, we enjoyed our stay and would recommend this apartment.
