First of all, If you have to go to the airport the next day I'd recommend staying in a hostel in Negombo or else you will have to take 2 buses or a long tuc tuc drive to get to the airport.
This hostel is a great place to start of your journey in Sri Lanka. The staff is nice(mostly backpacker who got stuck working there) so they can give you some advice on Colombo and Sri Lanka. Bed are good, Mosquito net, a light, and lockers are all there. There is a big common room with couches, a kitchen, an outside area, and another room with a tv with movies and a table tennis table.
There's a supermarket across the street and some restaurants nearby.
Location can be a bit hard to find for tuc tuc's but if you got the location on a offline maps app( like maps.me) it shouldn't be too hard.More
