For the location (city center) and it's price this is a good place to stay a few days.
The place is very clean and decently maintained. It should be noted that it is inside an aparthotel and the walls are pretty thin and you can easily overhear neighbors talking or whatching tv.
Because it is in the heart of the city you are within walking distance (15 min max) from almost everything a tourist can do in Heraklion and this is amazing. the drawback is tha the city center is full of bars that go on with loud music and singing well past midnight. If you are a loght sleeper this is a problem since, even with the closed windows it is noisy. you can drown the noise with the air conditioning, especially since there are moschitoes and you cant really sleep with the windows open.
The host is very, very responsive. we had a minor issue at chechin and he corrected it in less than 5 minutes. Also, this room had listed an oven but there was none and while we were gone exploring, in less than an hour, he brought us an oven. He is a great host.
You also have a small balcony where you can stay to have a cofee or sip a drink which is a nice bonus.
The bed is medium to hard but it felt very confortable, thumbs up for the mattress producer.
Overall I recommend staying here for the great location unless you are a light sleeper.
