Very good stay with Diogo, he is a FANTASTIC host. I would strongly recommend staying with him and his company at this or any of their listings. He was one of the best and most responsive hosts that I have ever had.
For this listing in particular, I would generally recommend it, but it wasn't perfect. Let me outline both the good and not so good points.
POSITIVES
1. As I said, Diogo is a fantastic and responsive host. After having used Airbnb for 20+ stays now, I find that the quality of the host is pretty important and Diogo is the best. Responds instantly, is very organized, always made sure we had all the info we needed in advance, etc... Just excellent!
2. House is a good size for 6 people. It has three real bedrooms and three real bathrooms. Was very comfortable for us.
3. Kitchen was very well equipped, had everything needed to cook. Pots and pans were very well taken care of. You can tell that they put a lot of care into ensuring that they maintain the condition of the cookware and other things. Very nicely done.
4. Location was good. A bit further outside the center than I would like, but very quiet and easily accessible. Close to two metro lines and a short uber ride away from most things in Lisboa. Lots of restaurants nearby and two supermarkets within 5 min walk.
NOT SO POSITIVE
The only major item is that there's AC only in two bedrooms. I'm sure it's fine 90% of the year, but the lack of AC in one bedroom and the main level downstairs can be a bit uncomfortable if the temperatures get to 90°F+. Diogo is a total pro though. He came and gave us fans to use to compensate for the lack of AC in some areas.
If I'm gonna nitpick, the bathroom in the loft bedroom (the nicest bedroom in the house) is ridiculously designed. No mirror, the sink is terrible, no ventilation causes condensation everywhere, etc.
Finally, I will say that the listing calls itself "luxury" apartment, and while I would absolutely stay there again, I don't think "luxury" is really an apt word here. Every piece of furniture (including kitchen cabinets) is IKEA. Looks fine, but some things are flimsy (as you'd expect from IKEA).
Overall, very good stay and an even better host!
