I always end up staying here -before and coming back- from the Islands, cause it’s just simply the best place for a reasonable price! Monastiraki is very close by and all the interesting sights in Athens are on a walking distance. If you like to hang out in the bars in Briki , it’s only a couple of blocks away!
Considering the price, standard is really good. I´ve always had a great experience staying at the Carolina! Rooms are clean, staff are ok and the reception is open 24h. Try to get a room with balcony or use the terrace on the roof! The rooms are small, be prepared!
Anyone that know of a better hotel in the same location and for the same price are very welcome to pass on that information :) !
