Belém was great, quick responses to all my questions even before I arrived. She had lots of great suggestions regarding food, markets and the sites. She even ordered me a cab to the airport at 4:30 am, so I would get to my flight on time.
The apartment was spotless, my room was cozy, I had my own balcony which was nice place to have a cup of tea in the morning.
The location was central, a few blocks from the subway, a park right up the street, restaurants and pastry shops all around. I will definitely stay with Belém again when I come back to visit lovely Lisbon.
Thanks for everything.
