What a great place to stay if you want a relaxing holiday Mary was one of the nicest people i have met and made our stay one to remember all the good points you read in the reviews are spot on and don't take any notice of the bad ones, Skiathos is the best greek isle we have stayed on... More

Just returned from a week here, everything just as we expected, friendly welcoming staff, immaculately kept rooms and pool, just a shame about the weather but cant blame the hotel for that!! The rooms have acquired a fridge since our last visit, another plus. a little more variation on the breakfast and it would be five stars but im really... More

First time stay at this hotel and would recommend it.Mary is very helpful and keeps things ticking over.Great location,very near the town centre.Rooms are very clean and perfect for people looking for a holiday in this price range.Family run hotel with some funny additional breakfast help in the mornings who also clean your rooms.

Our second time at Kostas & Mary and yet again we wasn't let down. Mary and Kostas and their family do a fantastic Job in keeping this hotel in the immaculate condition that it is and also the warming hospitality. Claudia at breakfast time is so friendly, if you are not a morning person you are best keeping out of... More

If I hadn't already booked next year's holiday I wouldn't be writing this review! We love Costas & Mary and have just returned from another wonderful holiday. Skiathos is magnetic and having tried many Greek islands, this one is way above the rest in cleanliness, friendliness and beauty. Costas, Mary, their family and the girls work incredibly hard to make... More

Had a lovely time again at costas and mary's. The place is immaculately kept. Towels and linen changed regularly (the towels are lovely and white). Every morning the sunbeds are washed down. Breakfast has enough choice - omelette and the usual eggs, ham and cheese. Geat location and lovely staff.

Skiathos is a wonderful magical place and this hotel truly reflects the spirit of the Island. Mary, Costas, her family and the wonderful team of Claudia and Valentina work very hard to make sure that your stay is memorable and pleasurable. We have never stayed in a Hotel that has been in a better location. A 5 minute transfer from... More

Costas and Mary cleanest, nicest, friendliest accomodation we have ever stayed in. Mary and all her family are excellent hosts. All the staff including Claudiolina (she says she has a big name so I have extended it) were also excellent. We have been on many holidays over the years (never Greece or the islands though) but Skiathos and Costas and... More

Not a bad word to say about Costas and Mary's. The hotel and it's ground's are spotlessly clean and it's location could not have been better. Close to restaurants, bars, bus stops and the port where all the day trips leave from. Mary is always at hand to give you advice and personal recommendations and all her staff are very... More
