I really enjoy the stay in this apartment. It is quite center located, about 10 minutes you can reach the metro station as well as the train station Rossio which you should go when you visit Sintra.
We are satisfied with the equipments and survives. There are two air conditions in the apartment, quite useful.
I highly recommend this apartment since it is tidy and clean. The cost is reasonable, if you have the chance to visit Lisbon, you should have a stay in this apartment.
