The Airbnb of André and Sandra is totally recommendable.
André and Sandra are really affectionate and anxious hosts.
Their amazing Airbnb leaves nothing to be desired: The bedroom we had is beautifully and stylishly furnished and has stucco decoration on the ceiling (and even prepared with little gifts like small shower gels and baby bottles of wine), the bathroom is very modern and clean (there's also a second small bathroom), the fully equipped kitchen and the dining table invites you to cook (we've regreted we didn't..we simply didn't stay long enough..) and last but not least there is a beautiful small terrace next to small local backyards.
The appartment is also very well located (10 min walk to Miradouro das Portas do Sol and Miradouro de Santa Luzia)
In addition to this André and Sandra wrote down their favourite places, restaurants, etc. in every part of the city (sent per mail).
Yet you have to be aware that they can be other guests as well, with whom you have to share the bathroom (it didn't bother us because everything was clean anyway). One last tip: In my opinion this is a perfect place for a group of friends.
I hope my long laudation ;) made you book this Airbnb :)
Have a nice holiday in wonderful Lisbon!
