We are a family of five and we loved this apartment. It has tons of character and some beautiful features - I loved opening the long window shutters in the mornings. It is very spacious and stylish with plenty of room for everyone to relax and do their own thing. The kids loved the tv room and we loved the kitchen and dining rooms. The location is superb, just a short walk to the metro and a few mins from shops and restaurants. Our daughters loved 'Retro City,' a vintage shop where we made several return visits - it's about a ten minute walk from the house.
We travelled towards the end of March and we found the Lisbon weather bright but cool so make sure to pack some warm clothes for the evenings. We would love to return later in the year to better enjoy the balcony in warmer weather.
