Louis studios really felt like home for us during our week long stay in Santorini. The beautiful property is managed by a wonderful family, clean, well-maintained and everyone is always warm and ready to make your stay comfortable. Everything works - the daily cleaning, the amenities in the apartments, hot water and water pressure, they even change your towels (beach/pool and in room) daily. Wifi works in the apartments and even the pool area well (was able to skype beside the pool) :) it's great for families esp because of the proximity to a less touristy beach and in the flatter area of the island (not as dangerous for kids). You can always rent a car or an atv to go around the island and the owners will help you arrange this as well. There is a store owned by the same family where you can buy virtually anything you need for your stay, incl fresh bread for breakfast, floaters and souvenirs. I cooked breakfasts everyday for my family during our stay.
There is also a small playground near. It is near Kamari beach if you like to visit the promenade full of restaurants and cafés but we preferred going to a local fish taverna called Galini, which is a 5-10 mins walking distance via the beach area. The food is cheap for the quality and the people are very friendly, great service too and really fresh fish. I especially have to mention how helpful the family is, they drove us to the nearest pharmacy for medicine when my daughter got a bit of fever too. All in all if you are looking for an excellent and relaxing stay with a very local warm feel to it, stay at Louis and skip the very touristy hotels. This one is worth it.
