If you are visiting Lisbon this is a fantastic place to stay. The hosts are wonderful and the apartment is sparkling clean and in an excellent location; truly centrally situated to many places you will want to visit. There's a nice coffee shop next door, a great place to start your day and Fabrica Lisboa down the street has a delicious breakfast. Rossio train station is a short walk for those going to Sintra. The tram to Belem is 5 minutes away. Solar 31 da Calcata has great seafood (go early or make a reservation) and O Trigueiranho offered delicious Portuguese dishes (cash only). Chapito a Mesa was another great restaurant. All short walks from Vitors apartment (along with many other restaurants but those are 3 we especially enjoyed).
We highly recommend Vitor's apartment for anyone visiting Lisbon.
