traveling to lisbon in august, looking for recommendations for a good hostel in the center of the city near the sights. solo traveler, woman in mid-30's.
your many posts are in the hotel "review" section. You may have better luck reposting in the individual destination Q&A sections.
You will find many good hostels in Lisbon city center.
I would specially recommend you these two:
Travellers House Baixa, in Baixa area, in street Rua Augusta - www.travellershouse.com
Goodnight Hostel, also in the same area - www.goodnighthostellisbon.com
Both these hostels are modern, clean, great staff, good price and nice private rooms.
