We have stayed in the apartment for 2.5 months (November - January). We are a couple with a small baby.
The flat is as described. Small but enough for us. We loved a big bedroom (it is very big!) as we had lot is toys and play mat for the baby and all fit in without issues.
We don’t cook too much but the kitchen has all needed for longer stay including a dishwasher. We loved a big fridge as had to store baby milk in it and it was great for that.
My husband worked from the flat and the internet has been great. He worked from the living room. In the bedroom the room was spotty sometimes but no big issues. Fast for working and reliable.
We absolutely loved the location. It is on a charming street in touristic area but it is not very noisy or crowded. Close enough for restaurants, cafes and centre without feeling like you are in the middle of the crowd. The city centre is also a short walk away (15 minutes or so). Of course it is hilly but that’s a given in Lisbon 🙂
