This place is a gem in the city and we really enjoyed our stay there!
It is located in Lapa, safe and not far from down town. It is on a secondary street which makes it very quiet and with a 2 minutes walk you can basically reach anywhere in the city by bus and with tram (few more minutes walk away).
The flat is practical, well-equipped and good also for families with kids. Bery nice to have Wifi available and a key-free lock to enter the flat!
We had some issues using some electrical appliances at the same time but we understand that it is part of standard electricity allowance in Portugal
I would definitively recommend this flat and if we will ever be back in Lisbon, we’ll know where to stay :)
