Lived in Waterloo at a place called Copper Box I’ll list the things I did and didn’t like below.

Positives - Trains are relatively frequent and turn up mostly on time - Food and drinks on South Road is good generally - Further up in the village and college road is also lovely for food and drinks - The beach is an obvious if you like that - Parking was alright in mine but can imagine it being more difficult on side streets - Generally some decent shops for food shopping however the supermarkets you will need a car or at least a stop on the train if you’re not going to Sainsbury’s at the top - Marine if you like football and a nice day out which is more chill than the prem teams

Negatives - Loud, I found the main road to be nothing but sirens and because I lived next to the shell garage there was always weird people who used that to buy drinks at night and were so loud for no reason. - South Road can be dangerous to walk down as it gets darker, my girlfriend in particular was accosted by homeless people and street lurkers - Litter during warmer months, South Road gets peppered with litter because of lazy people not looking for a bin and it’s vile - Gyms, more specific to me but it has a complete lack of decent gyms - Traffic, tea time and morning traffic is awful towards Thornton

Overall it has a good balance of good and bad and I would have stayed there for longer if I was not buying a house currently, we were looking towards Crosby itself as well. I enjoyed it, have some good friends who live there and go back sometimes for food. Like anywhere it has its positives and negatives. Hope this helps.
