Isabel met me when I checked in and showed me the apartment. She is always available and also gave some good recommendations when it came to local restaurants, both in Lisbon and in Sintra.
The apartment looks very new, and has a modern feel to it. It actually feels larger in real life than in the pictures.
The bathroom is very nice with a comfortable bathtub.
Locationwise, the apartment is very close to everything, situated close to Rossio Sqare, both Bairro Alto, the train station and the old town is within walking distance.
I highly recommend staying here!
