Had a wonderful stay at Elvira's hostel.
It's located 5 minutes walk from the central bus station and 2 minutes from the heart of Agios Nikolaos. The room was clean, larger than I expected, with a little kitchen and fridge. The bathroom is spacious too. The room also has a little balcony overlooking the street, which is very quiet even during the day. On the other side, the room leads to a very nice common area, with few tables and chairs where you can chill and relax while enjoying Crete's breeze.
Elvira is very nice, smiling, easy to comunicate with... a perfect host!
