We love this place, we've stayed 4 or 5 times over the past few years, both with friends and as a family.
The apartments are a great way to have the freedom and space to enjoy Liverpool. Our last stay was in one of the massive penthouse suites (we've stayed in 2 of them, go for the red champagne one) The styling is very trendy and modern, kitchens have all the appliances you could need - so a great place for a celebration.
Parking is ideal as they have their own underground and are quite happy for you to stay there even after checkout time. The addition of two restaurants downstairs is a great bonus - make sure you choose a room higher up as we did experience a far amount of kitchen noise in one room.
Being where it is, so close to L1 the street noise can be quite loud, but if you're out partying yourself it really isn't an issue.
Great location, great apartments, great prices.
