Great place and great host !!!
We loved every minute of our Lisbon experience and Ricardo's place was the best place to see it from.
We had most of the city in walking distance ( if you enjoy walking a bit more than usual ) and there was also great public transport nearby ( bus / subway ).
The apartment was clean, welcoming and comfortable. The decorations were unique and made us feel like home.
Ricardo was of great help suggesting good places to visit or eat. He was helpful with every question we had.
If you ever want to visit Lisbon, this is the place to stay ;)
