Very minimal annoyance: the bathroom shower is leaking so, during the first time I went showering, the bathroom got wet all over because of the leak. Also, the WiFi signal was kind of weak in the farthest corners of the cave rooms.
This cave hotel is located in the heart of Urgup town, which is 10KM away from Goreme (the main sight-seeing destination in Cappadocia). It is a family-run boutique hotel with 4 lovely cave rooms and complete with amenities like WiFi, cable TV and comfort room with toiletries. The breakfast, though very basic, was unforgettable because of the cozy feel in the balcony of the hotel. Lastly, and most memorably, the owners of the hotel were very warm, accommodating and helpful (even they had difficulty speaking English). Their exchange rates are exactly the same as the daily rates (so it means, they don't earn from it!). And they have a very cute baby boy who's smiling all the time! Plus, the Hamam (Turkish bath) is just a few steps away from this hotel.
