This is a great apartment for a family of 4. All four of us are adults and we could manage here successfully.
The apartment is located at a very centralised location. It is walking distance to a tram station and the Southern Cross railway station for long-distance travel. Very good cafés nearby add the city flavour to the vacation stay.
The rooms are small if you have big bags (like we did), but it can be managed by using the wardrobes effectively. Moreover, the apartment has one bathroom only (as described correctly in the listing) and it can be a problem for some where all 4 have to get ready early.
Our check-in process was problematic. As per the instructions, we were supposed to pick up the keys from a lockbox that was in the side alley. However, we found that the lockbox was broken when we reached at the location. Upon informing, the host arranged a spare key immediately and also replaced the lock (for safety reasons). The hosts were very responsive and took good care of us in solving the problem, but we lost one hour in the process.
Barring the check-in incident, we had a great stay there and we would stay there again
