We stayed here for 5 nights as a family with my two adult children. This is a great central location and for us who love to discover new places upon foot then I highly recommend the location of Ricardo's apartment in Barrio Alto.
Ricardo himself is a great communicator, always quick to respond and at hand for any questions.
Staying in late January we had lovely weather and I think a great time to explore Lisbon and Sintra.
The best thing about this place was the bedding arrangement. With my son and daughter travelling with us each was able to have their own room. One tip, the front room is susceptible to noise from the street; usually passer byers returning after a late night out. No bars as such in this Street, so generally very quiet and whatever chatter is short.
We hope to be back soon.
