We stayed here for 4 nights in April. There were four of us. This place actually has 3 bedrooms so it can sleep up to 6 people and there is plenty of common space room for 6 people, plus good size bedrooms. The master bedroom and bathroom are very large and wonderful - I wish my bathroom at home was that large!! The second bathroom is definitely smaller - though broken into two rooms - one with sink and toilet and another with shower and sink - which is kind of nice if multiple people are using it. We were there with my daughter and her boyfriend and we were paying for everything, so it worked out perfectly - but if you are there with 2 couples or 3 couples - i would suggest that couple staying in master pay a bit more than others.
Apartment is beautifully decorated and very spacious, tons of bright open windows, and well stocked with all kinds of supplies for the kitchen. It said on the site that the washer/dryer was in the building, but there is actually a washer/dryer in the apartment. Great towels and very comfortable beds.
We didn't meet Stephanie as she was out of town, but her assistant Fatima was fabulous. Responded quickly to my emails as we coordinated when we would be arriving, and she saw the taxi dropping us off on the corner and came outside to help us bring up our luggage. We didn't have any need to contact her while we were there, but she offered for us to contact her if we needed too.
Excellent location - basically located on the corner of a nice square, in the flats sort of right in the middle of everything - up some hills to Alfalma on one side, up some hills to Chiado/Barrio Alto on the other. Straight flat walking to the ocean. The hills really aren't too bad and we walked almost everywhere. There is a small market just a half a block away and other shopping nearby for anything you may need.
The only negative at all was that the door to the apt and the entrance door from the street were both a little difficult to open. Just practice knowing how to open with the key before you leave for the day so you don't struggle when you get back the first time. They are putting in an elevator, though it wasn't operational yet when we were there, but this apt is only 1 set of stairs up so the elevator really isn't necessary for this apt.
We loved this place - the pictures are true to what it actually looks like, and I think it is even larger than what it looks like in the pictures. Do not hesitate to book this apt and enjoy your stay in Lisbon!!
