Please don't be put off by what I said. There is a bedroom with two single beds (push them together and you get more space....lol), wardrobe, dressing table and armchair. Also a separate little kitchen with fridge, cooker etc and a shower room. Providing you were tidy and organised I don't think it would be a problem. You also have a balcony with table and chairs. There is not a huge amount of storage space but to be honest there isn't in any of the self-catering Greek studios.
It is on three floors....obviously the top two floors you have to go up the stairs but if you were in the lowest one, there is a big area outside on both sides which would give you more space to "spread". May shouldn't be too hot and those studios are well placed because they open up east/west so you never get the heat of the midday sun.
There is a lovely swimming pool with separate children's section, sunbeds etc and highchairs in the eating area. The food is very good and not expensive and you are a five minute walk from the beach. My kids love(d) it there and will be back this year even though 23 and 25 now! Jimmy and Spiros run the bar (Rainbow) and they can't do enough for you..
My advice....go for it! Go for Dionyssos 2 rather than 1...they are nicer
