We had a great stay in Mornington, the apartment is in a great location - only a few minutes walk to the beach, or to a large park, and the main strip of shops. The apartment feels private, and is in a nice quiet spot, with a lovely garden to look out on. Plenty of space for a long weekend away.
A big draw for us was the full size cot (rather than a travel / portacot), and the space is baby friendly. I will say though, if you or your baby need total darkness to sleep, the blinds do let in a lot of light so bringing something to block the windows may be a good idea!
Would definitely stay again and would recommend to others. Thanks Kim!
