I had a really nice time in Oscar's room. The hole apartment was as it appears in the web and my room with all the facilities I was looking for (big bed, TV, WI FI, window) and clean.
The apartment was a five minutes from the city center and offers la opportunity to walk around discovering the great Lisboa.
Oscar was very helpful, charming, amiable, friendly, courteous, polite and well mannered.
I will come back.
