The appartement ist perfect for 3-4 persons.
It is really close to Rossio station and the main station. You can walk to all the sights and a lot of restaurants and bars are also in walking distance. There are also different supermarkets just a few minutes from the appartement.
Communication was perfect! Liliana and her collegues answered so quickly and helpfully.
We had a great time there and I really recommend staying at Liliana's place!
