Claudia was an absolute dream host, we couldn't have asked for a better place to base ourselves for a long weekend in Lisbon. She was extremely accommodating in getting us checked in after our late arrival (due to a plane delay) and in letting us leave our bags a little later after we checked out. The flat was great for four of us, and had everything we needed - the coffee machine and tea bags were a nice touch. We were well located near Rossio station (for the train to Sintra) but mostly we walked - lots of hills in Lisbon, so come prepared with sensible shoes!
