I was impressed the flat is at least as great as it looks like on the pictures. You will enjoy the very spacious terrace in this all new flat. At 1 minute from subway and buses station and 5 minutes from a big mall, you will love this quiet place for your trip in Lisbon for sure. Though we arrived very lately, Diogo and Johanna were very welcoming, full of little attentions so that you feel like you're home the second you come in. I do recommand this flat for your trip and if I had to go back to Lisbon, I would definitely go back to this place.
Nowadays it is so rare to find something better than you expected that you cannot miss this opportunity. Go to Diogo and Johanna's apartment ! That would be my advice !
