First, the host, Isabelle. She was fantastic; helpful, friendly, never intrusive, but always there when needed.
My friend and me enjoyed 8 days in the indeed cosy, clean flat with more than beautiful view to the Tejo river. It is not big but you have everything you need in it and most of all, a lot of brightness that makes you feel good and happy. The area is silent and you hear birds day and night, what is so calming and relaxing. You enjoy the first cup of coffee looking at the beautiful red roofs and the river. I was taking a photo from the window several times and each time it was the same view. Of course, the photos were just like each other (sometimes with a ship, sometimes without a ship in the river). I just could not help admiring the beauty of the view.
The location is perfect; you can take a nearby metro, bus or a tram to go wherever you want, but you can also walk downtown if you like walking and have time. Nothing is too far from this spot. Besides, the area is very interesting with narrow streets and old colorful houses. You can discover beautiful spots near by.
In Lisbon, I'd always stay in this apartment and warmly recommend everybody to choose it without hesitating.
