We had a great time at Ricardo's apartment in Lisbon.
We were greeted in a late night hour by Ricardo's sister and her husband, who were very welcoming and helpful! It was surely an ideal starting point of out tour in the city.
The flat itself is located in a central location in Alfama, where you can hear Fado music on the balcony from the adjacent restaurant. The big plus: the music stops around midnight (unlike other places in the area where the music goes on till 4:00 AM), so you can have a good night sleep.
Overall, we had a wonderful experience and we highly recommend the flat!
One thing you should know though: the stairs are somewhat steep, so it might not fit a person who is physically disabled or having hard time in climbing a few floors.
