Centrally located and literally next store to a great little bakery, this apt was great! We stayed here for 6nights and enjoyed how close this place was to the metro, trolleys, trains, walking to the river, eateries, and sights. From here, we easily caught a train to Cascais on one day and Sintra on another.
Perhaps the only thing to be aware of for light sleepers is the fact that with being centrally located comes a bit of noise. The windows and shutters block out much of the noise but if you have trouble sleeping with any noise at all, then you may need some earplugs and white noise until about 2am.
Being our first trip to Lisbon, we were surprised at how much we enjoyed the city and culture. It's now at the top of our list. When we come back, we'll definitely stay in Vilma's apt again!
