I've stayed at Agostinha's place 3 nights and that was a great time! She is an excellent host, really friendly and helpful, making you feel like at home. We've been offered a detailed information how to find our way around the city, what to see, where to eat.
The apartment itself is really nice too! It was all comfortable and clean with big kitchen to share. It's situated around 5 min walk from metro station, which is a big plus. Also the area is really calm, so nothing interrupts your rest at night. Thank you and all the best for you Agostinha!
