I would highly recommend Ines and Manuel’s lovely duplex apartment to anyone visiting Lisbon. We spent the Christmas holidays there with our two kids. It is comfortable and bright with plenty of space for gathering and also spending time apart. The owners have thought of many details, even including slippers for their guests. We woke up each morning to church bells. The iconic 28 tram line goes right in front of the building and there is a street with shops a two minute walk away, where you can buy metro and train tickets. Manuel was extremely responsive and attentive, even considering it was Christmas and his wife gave birth to a new baby during our stay.
The apartment is on the top floor of a walk-up building so may not be ideal for young children and people with mobility challenges, but we found it quite manageable with our 10 and 12 year olds.
