To highlight the positives, the experience of spending a few days with the family of Reverend Zach and Ramani was as charming as a homestay experience is supposed to be. The warmth of sharing a cup of tea on arrival, the piping hot breakfasts that Ramani prepared every morning, and the dinner that we had with them the last evening, were all parts of the treasures that we accumulated during our two days of stay with the Koshys. The 'home' part of the homestay worked out just beautifully.
However, on the more practical aspect of it, the 'stay' wasn't as comfortable. The room was very small for three persons, with hardly any space left for moving around after three beds were laid out. The beds were smallish (not meant for anyone over 5'9"), and the hot water supply was simply inadequate (no geysers). A couple of light-bulbs in the room were found to be fused on arrival, and they stayed like that throughout the two days of our stay. This was one of the more expensive properties that we stayed at during our Kerala vacation, and even then it lacked in basic comforts.
This also lacks a space for the driver to sleep in, and the driver has no other option but to arrange for his own space (or sleep in the car). This isn't something that would make a conscientious traveler happy, especially if you've been traveling around with a cab for over a week and want your driver to have basic comfort.
