Really great apartment! It has everything you need. You're close to the train and metro station (it takes around 15-20 minutes to get into the city center) a supermarket (5-10 minutes to walk) and restaurants.
The only issue for people with a light sleep might be that you hear landing plains. We had ohropax and it was absolutely fine for us.
Sofia is a great host and can help you basically everything. She responds super fast.
We can absolutely recommend to stay at her place when you want to visit Lisbon.
