I will be no exception to the ones who wrote a positive review before me.
My experience at Catarina's flat was great:
- the area is really cool (organic food market on Saturday) with a lot of things that can be reached by walk
- the flat was clean and comfortable with a great view on Lisbon and the Tage
- two super hosts: Sandra first gave me the keys and allowed me to find out a unique restaurant; then Catarina took over and we got along very well. Both were very understanding and flexible.
I fully recommend this flat and shall come back (and soon as I can fly back to Lisbon:)).
One comment: there is no kitchen per se but everything you need to prepare breakfast. However, food is so good outside that you won't need to cook :)
