Having lived at many airbnb apartments in the center of Lisbon, I lately opt for the ones a little away from the touristy center. Filipe's apartment was not far from downtown Lisbon, but also in a very quiet place, overlooking a beautiful park, just 5 minutes away from a shopping center and a large supermarket, 15 minutes from the train station to Lisbon and 10 minutes away from the beaches.
The apartment was impeccably clean. I can usually find something that's been overlooked by the maid, or just a lonely hair in the bathroom, but no, no such luck this time ) The bathroom and shower were modern, the bed linen comfortable, the kitchen had more than enough to cook a nice dinner for guests, and even plenty of condiments, tea and coffee.
I especially liked to work in the little sunroom, where it's warm and cozy.
Filipe was always just a call away, he was so very kind letting me check-out a day late for a fraction of the cost.
Very highly recommended!
