Extremely sorry that your experience was very bad. We cannot apologize enough for the same.
1. Information about network coverage: We typically inform guests specifically with A FAQ that explains everything that may be important including the network coverage. Idea and BSNL (to some extent) have good coverage, other networks do not work. In you case you had done an instant reservation and hence we missed out on exchanging that information. No excuse, this means that we should be sending the FAQ explicitly later.
2. Cleanliness: Cleanliness cannot be compromised and we are planning to replace the caretaker soon if this is not taken care of.
3 Availability: We could not take the call from the caretaker as we were attending to our daughter in a hospital. We tried to call you later but did not realize that you were unreachable since there was no network coverage. It was good that you found our previous information helpful.
All in all, sorry for the experience. AirBnB is a wonderful portal and hopefully you will have better experiences. As for us, it is time to correct our act, no excuses.
