Nikolas was a great host and a great person :)
We had booked the room from August 24th until August 29th. Our plan was to arrive at the island of Astypalaia on August 24th at 03.30am, have a small tour and wait for the new day to begin so we can get settled in our room. But this was our initial plan. During our trip, Nikolas called us and gave us a nice surprise by letting us know that he would pick us from the port and the room would be ready to host us by the time we arrived at the island. It was also a great surprise that Nikolas didn't charge the additional night.
The house was clean, tidy, very cozy and with a great view. It was spacious and comfortable for 5 people. Fully equipped kitchen, bath towels, laundry detergent and every thing you may want for your everyday needs. Although there was no A/C, the house was cool and each room had its own fan.
The fridge was full of things for breakfast plus some beers and a Caprice box(chocolate sticks) in the refrigerator(that was more than awesome).
The house was in Chora max 3 minutes walking distance from the main street of the island and from the castle, respectively.
I strongly recommend Nikola's House!
