We stayed for 3 nights during October, with our 9 month old daughter.
The apartment is very nice! - clean, comfortable, roomy! Fantastic location in the old town right above a very lively street packed with bars and restaurants, yet the apartment is quiet!
we have not met Vagelis however his friend assisted us upon arrival and departure,and his family ( especially his mother) have been very helpful as regards our baby's needs. Vagelis was in touch with us during our stay to make sure all is well, and clearly cares very much for his guests.
Baby-wise: there are quite a few steps in the apartment and also going into the apartment from the street, so managing a stroller is a bit tricky.
To conclude: a god choice for accommodation in Chania, we highly reccomend!
