After having a lot of good meals (so far the best food I had by the beach in Unawatuna) and sunbathing around, decided to move to the guest house and stayed for 2 nights.
Mainly because was literally on the beach (which was recently renewed, longer and with golden paradisiac color), fast wifi, friendly staff and amazing place to chill during all day for a quite affordable price. The room was really good, AC, nice light and comfy bed! Plus they have international channels by the restaurant, which is good for someone that follows football so you won't miss the big matches.
Definitely recommend it!
