One can book their stay through online bookings or can check whether it's included in their tour package. It can be accessed through nearby cities such as Kottayam, Alleppey, Ernakulam, Kumarakom. They have AC and non-AC types of room. Standard houseboat stay starts from price as low as 900 INR (non-AC) and around 1500 INR (AC) per person per night. Deluxe houseboats, especially for couples and families, cost more than 2000 INR (AC rooms) per person per night. Prices may change according to the season. All types of food, with breakfast, lunch & dinner are made and served on-board. WiFi & TV services are available but depends upon network availability.
In my opinion, it would be the best option for the stay during the lockdown, away from the heat of the cities, one can resides in the nature covered by lagoons!
