Generally I don't like these chain hotels - but if I have to stay in one of them then Treebo is preferable to Oyo. The basic business plan is the same but, based on my experiences thus far, Treebo rooms tend to be slightly better standard and better maintained. This one was quite convenient to CCU airport - I got an Uber from the airport to hotel and an Ola cab back to airport and it was less than 10 minute journey. One drawback is the breakfast was 'pure vegetarian', and in India eggs are regarded as non-veg, so there was no source of protein, vegetarian breakfasts in India are generally quite unhealthy.
