There are only a few places in the world where you can stay in a cave room. Cappadocia in Anatolian Turkey is one such location. The timing was such that my trip to Cappadocia coincided with my birthday and hence I ended up upgrading myself from a typical hostel to an awesome cave room. The cave room that I stayed in was at the Goreme Mansion in the town of Goreme, one of the top hot spots of Cappadocia. I stayed here for 4 days and 3 nights and the below review is based on this experience of mine.
1) Cave rooms are very unlike traditional rooms. They have all the modern facilities, have low ceilings, walls coming out at places and limited air circulation. But, that is also the fun of a cave room. The cave rooms at Goreme Mansion were like this. If I remember right, the rooms cost me about 40 Euros per night.
2) This place is run by a local family who take good care of you, help you answer all your touristy questions and also throw in some tips. While the husband and wife do not speak English, their son and their front desk manager speak good English.
3) The homestay offers free traditional Turkish breakfast that is wholesome and delicious. They do not serve any other meals.
4) They offer free wi-fi around the clock.
5) In terms of proximity, they are located at a short walk from the bus station and most of the restaurants, supermarkets and shops of Goreme. One can even walk to the open air museum from their place.
6) The homestay offers tours and takes bookings for balloon rides. Personally, I did not take any of their tours.
7) The rooms are temperature controlled, have hot showers and have comfortable beds in a reasonably spacious setup.
If you are looking to stay in a cave room and wish to connect more with a local family, I would request you to give Goreme Mansion a look.
