I enjoyed the stay in Ericeira, the staff was very nice and the atmosphere with the other guests was great. I am disappointed by a couple things though, n#1 being the bathrooms, that were moldy and disgusting?! I was really unpleasantly surprised by that and it definitely made my stay uncomfortable in that regard. Also the storage space is super limited, the lockers are too small to fit a suitcase or a backpack so bags were lying around everywhere in the dorm... I was also very disappointed that the kitchen was so small and that there were absolutely no place to work besides one phone booth. The place definitely looks much bigger on the pictures but in reality is a bit packed, it's perfect if you want to meet people or if you only stay for the night, or when it's warm there are bigger outside spaces, too. It's well located too, uphill just next to the supermarket and a big retail store. Beds are clean and comfy and i slept tight.
Overall the place is pretty and well kept aside from the bathrooms, there is a great atmosphere; if these couple things can be improved, it would make Selina a great hostel.
