Tasos is a very nice host. He and his employee Jeórjios (who speaks perfect German) were always very friendly and helpfull.
We stayed in two of his appartments. Two days in a one bedroom appartment and one day in a two bedrooms appartment. Both of them were very clean and had everything you need. The rooms were really spacy, modern and comfortable. They have either one or two terrace or at least on balcony (if your room is on the first floor).
The studios and appartments are located around 3 pools (one of them were empty at the moment) and a little poolbar, where you can drink or eat something or only sit there and enjoy the nice wheather. There you can get free Wifi, too.
The complex (called Gennadi Garden Appartments) is located at the south of Gennadi, which has a supermarket, a bakery and some other shops and taverns, where you can buy nearly everything you need. It's only a 2 min walk away from the appartments.
The beach is a 5 to 10 minutes walk away from the appartments and there you will find a mixture of sand and (very) little stones. The beach was surprisingly empty. Even at the main season. We just took a towel with us, but you can also rent a sunbed and a parasol at one of the taverns at the beach.
Altogether we really enjoyed our holiday at Tasos' Gennadi Garden Appartments and will definitely come back soon.
