We had a great stay at Philippe's place during our recent trip to Lisbon. The place was very clean and very tastefully decorated. Susana warmly welcomed us when we arrived from the airport, showed us where everything was in the apartment and most importantly showed us how to use the speaker for music.
The apartment is on a lovely little hill with great views and a less than 15 min walk downhill into the city. We really loved the Graca area and this apartment - couldn't recommend it highly enough.
