Loved my stay in Lisbon!
Highly recommend this hostel! 👌🏼 The staff are friendly and most speak English and/or Spanish so you have an option in case you struggle to communicate in Portuguese. There is no pool but the outdoor space is wonderful and beats most hostels that have a pool option tbh. You're right in downtown Lisbon with so many amenities within walking distance too.
If you come alone and are looking to make friends and enjoy the nightlife, you can do the Pubcrawl option and go bar/club hopping with a bunch of ppl from the hostel for 18 euros. Highly recommended because there's an open bar option as well. There are other activities to join such as the boat cruise too.
