Staying at Anna’s hostel was great ! The hostel is clean and well situated : it is easy to come from the airport and it is not that far from the historical center of Lisbon (especially if you take the subway). It is also well equiped, you can cook your own meal in the kitchen. The terrace is beautiful ! The other travellers were nice and respectful, no problem to share the common spaces. There is also a cat which is very nice. I will come back here if I return (and I sure will) to Lisbon ! Au plaisir !
