We stayed here for one night, after arriving on a late night ferry ride from another island. The flat is located in the heart of Heraklion, within minutes walk of the Lion's Fountain and the venetian harbour and fortress. It is approx 5-10 min away from the port by car (taxi is 10 euro fixed price from port into city apparently).
The flat itself is very clean (bedding, kitchen, bathroom) with good A/C and amenities. The balcony overlooks a local restaurant (nice to sit and watch people) and not too noisy (at least for us) at night. Enough space for two of us.
One of the best things is that the flat is literally next door to Peskesi, a really good Cretan restaurant with excellent food and wine, and local coffee shops. Ilias was very responsive as a host, checking in with me during my ferry trip to confirm arrival time.
I recommend this flat for short or longer stays!
