Antonio and Martinho's apartment was amazing for multiple reasons. The location is great: 5-minute walk to the Intendente station, the neighboring streets (and apartment building) are quiet at night, and my travel companion and I felt very safe walking home in the evening.
The apartment itself is on the third floor overlooking the southwestern part of the city, and we spent a lot of our time in the apartment sitting and staring out the big windows. The view is beautiful!
Antonio and Martinho met us in person at check in and were very friendly and welcoming, and I appreciate they took time to show us a map of good spots for dining and watching the sunset. They were very easy to communicate with and very quick to respond with answers to my questions ahead of our visit.
The apartment was clean and well-decorated and more than enough room for two people. There is a full kitchen, big dining table, the bathroom is humongous, and there is also a washing machine. There is also an AC, but with all the windows we were quite cool using just the fresh air. The personal touches were also very nice and thoughtful — clothespins for hanging laundry on the drying line, a complimentary bottle of wine, etc.
I would stay here again and have already recommended this spot to friends visiting Lisbon later this year.
