We had a wonderful stay in Lisbon. We enjoyed the portuguese food, wine and honest, friendly people. We can highly recommend a day-trip to Sintra.
The communication with the host was without any problems, there is a 24 h check-in possible, because of the code you had to enter to open the doors. Also we were very happy with the comfy and clean bed and the perfect(!!) location of the appartment. The Wifi and TV with several programms does work without any problems.
The only thing the hosts could work on is the presentation of the appartement: maybe there are some things they could add or change to make the appartement more cozy and inviting.
