My partner and I stayed at Vera and Joan's place for a week. From the moment we arrived they made it seem like home, spending the time to go over that must sees and what was happening in the area at the time we happened to be there. Thanks to the introduction that they gave us to the city we had a new event/attraction to visit each day with no planning (and that is really the way that I like to spend a holiday).
The appartment was clean and central. The food they provided lasted for a number of breakfasts and snacks and there was not a single thing that I could fault as missing (three options of coffee makers is also a big bonus in my books!).
Additionally through running into Vera in the streets a few times it really made the place feel like home with a sense of community.
I highly recommend staying in this appartment and hope that you enjoy your stay in beautiful Lisbon. I know that we will be back!
