My friends and I, we stayed for 2 nights in Juva Camping. We booked a cottage for 4 people via e-mail to Markku (the owner - he was very nice). It was 55 euros per night (sauna included). There was a kitchenette in the cottage (electric wave, microwave, dishes, frige). Toilet and shower in the cottage. Linen is not included. The camping is well situated near a big lake. And you can visit Savonlinna castle (about 60 km).
