Originally was going to stay only 1 night but decided to extend to 2.
I usually only book my first night in a hotel until I can see the condition before deciding to stay any longer, but if you are like me and are considering staying a few days in Cochi, there's no need to hesitate to book multiple nights at the Sonnetta Residency.
For me, the important things in accommodations are: a clean bed, good wifi, a good location, and if possible breakfast included and Sonnetta had all these things.
Breakfast was a little simple, coffee, a few toad with jam and a banana, but that's pretty much what I eat on any weekday when I'm at home.
Across the street from Sonnetta is a pretty good restaurant as well, with chairs laid out on a terrace.
The manager, I didn't get his name, but he genuinely seemed concerned about my comfort/happiness more than turnover and the business aspect as is usually the case in India.
A tip for getting there from Ernakulam junction station. Take the ferry to Fort Cochi.
Ferry pier is about 15 minute walk from train station, or 40 rupee tuk-tuk, then a 6 rupee ferry ride to Fort Cochi, then another 15 minute walk from the jetty to the hotel. Just ask around for "princess" street, everyone knows where it is.
I would not hesitate to stay at Sonnetta Residency again.
