The place was very clean and I have nothing to say about it that is not already mentioned in the description.
All the less enjoyable things are my fault, but I'll list them here in case readers can learn from this.
Flavio was very reactive and flexible, and gave detailed instructions over a famous messenger app (WA)
This is a pro and a con at the same time because I had some bad luck and could not really watch the video on WA when I arrived in front of the door.
I was attending WebSummit at the Altice Arena, and I chose that place based on a quick look at the proximity to the highway.
This place is very convenient when you come from the Airport by taxi (I recommend using taxis over Uber), but has a few drawbacks when it comes to attending WebSummit:
1. there is no metro station reaching Campo Ourique, you'll have to take a bus or the trolley to reach it, and they are slow and not frequent (especially in the holiday period).
2. Roads in Lisbon can be very uphill and pavements are not smooth, so electronic bikes are not always nice to take.
You might think that it's ok, as long as Uber can take you to websummit, but bear in mind that 70,000 people are attending, hence, Uber are overprice during that week and take very long to come, since Campo Ourique is at the opposite of the Altice Arena. Morning traffic on the highway is huge.
So in conclusion, it was not anecdotal that no Metro was closeby. It really prevented me to reach the Altice Arena quickly, but again, that's on me.
Also, I don't know whether that's true everywhere in Lisbon, but the airplane are flying very low and you could here them quite a lot from this Airbnb.
Again, this comment is just to help people understand that depending on their goals in Lisbon, this place can be very convenient or have slight drawbacks, such as the location.
