Hi Frigate
We've stayed at Tsaros Studios both last year and this. Nikos picks you up from the coach at Barras in the centre of San Stef in his minibus and takes you right to the studios/apartments. Last year we had room 4 - one bedroom and a kitchen - whicht I suppose would be called basic - but perfectly comfortable and adequate. The kitchen has a hob, fridge, kettle and toaster. The bed in room 4 is a double; in room 3, the other studio in that block, it is twin beds. The balcony over looks the gardens, with views over San Stef and the surrounding countryside - you can see the sea and the mountains of Albania! The window to the bedroom looks onto the lemon trees.
This year, Nikos gave us a choice of rooms as a returning guest - and we chose room 4 again! Thannasis had a glass of Mythos waiting for us at the bar. The pool area is very relaxing, again with great views over San Stef. The hill isn't really a problem - and Thanassis sells packs of water, so you don't have to carry them uphill. You can walk up the hill from the studios to the footpath along the cliff-top to Arillas - don't let the Thomson rep dissuade you from taking the path - its perfectly safe, and there is now a new snackbar before you drop down to Arillas which is well-placed for lunch.
I would thoroughly recommend Tsaros Studios - we will be returning!
