We staid one week in the flat with 2 kids (8 years old and 5 months old) late March. We liked the flat, it's a renovated old place, very well located, very charming old style place, well equipped (IKEA furnitures/dishes/appliances), everything around (pastelaria, groceries, resto, bars, market time out, train station...). Relatively quiet considering the location which is the heart of the Lisbon night life. The only bad point was a smell coming from the bathroom sink (which was clogged) and spreading out in the whole flat when bathroom door was open but we signaled it and it should be easy to fix before the next guesses are coming.
