This clean and well located hostel was exactly what I wanted as a 39-yr-old solo female traveller. I liked my 4-bed female only dorm with a cosy bed and plenty of space under the bed for my suitcase(but terrible pillow!) with shared bathroom, cabinet and body wash, table and chair, lockers and a bedside drawer, charging points, small balcony and invaluable aircon in 34 degree heat! Met some friendly, considerate ladies and the lift was handy to the fourth floor, although it took some getting used to!
Reception service was good, supplied an iron and luggage storage on last day with a late flight out. Towels charged at 2euros so take your own as well as handwash and toiletries! Free breakfast of tasty croissants but milk for coffee was awful but I found a fab cafe just a few doors to the right. The outside garden was small but noisy, full of young kids mostly so unable to read my book.
There are cheap restaurants directly opposite, but the food was poor on the whole. I did find an excellent souvenir shop around the corner and a lovely patisserie and local cornershop for cheap bottles of water and supplies.
The best thing was the local train station about 15mins walk from hostel. I bought a week's pass for 25euros and got to all the sights (Colosseum, Trevi Fountain etc) in just a few minutes. I also easily booked a bullet train to Venice using an online booth, though the queues are massive at any time of the day!
Safe, cheap, cheerful and brill transport links!
