Based on relative value and the marvellous Jo, I have to give 5 stars.
The location is a 5 minutes bus ride from the centre where the amazing public transport can take you anywhere; Zone 1 covers the city, via buses, trams, tube and boats out to the islands.
Jo's flat is part of a gated community with a small playground and picnic area, there is a bus stop outside one of the three gates with regular buses to the Central Station. There is also access to a restaurant, I didn't eat there but it looked nice.
The flat has a functional kitchen and an excellent shower and bath, and a separate WC, the living room has a large TV with Chromecast and Netflix.
A washing machine but no drier, but there are airers.
Jo clearly loves music, though we didn't figure out how to use his great speakers.
The best thing about this Airbnb is Jo, who is lovely, bubbly and quick to help, though sadly, we didn't get to meet him.
