We stayed in the apartment for 3 nights in February. Location is perfect for exploring as it's within walking distance of the Castle, other sites and the metro is only a few minutes away. Apartment was modern, clean, tidy and provided a nice quiet space to relax after busy days exploring.
Margarida made us feel extremely welcome and showed us all the local a amenities as well as where everything was in the apartment, which was extremely helpful.
I would thoroughly recommend staying and would definitely look to book the apartment again when we return to Lisbon in the future.
