We were in the older apartment (there's another one besides on which I cannot comment). This older apartment was clean and ... well some may describe it as "cozy", others as "quaint" but we tend more to the statement of "cluttered" . We were three people and had trouble to rearrange all the chairs / cushions / stands etc to find space to put our three suitcases down...
It's just a 10 minute walk from the apartment to the metro and thus you are in 30 minutes (in total) downtown. It was easy to find street parking.
It was quiet at nights and over the weekend - however very noisy (sledgehammer, hammer drill etc) from 8:00 am for the working hours during weekdays. I trust they will finish some time and thus this should be of no concern for future visitors.
Of serious concern - especially if you intend to bring kids - were two live power points hanging out of the wall on bare wires (though I'm sure they will be repaired soon after we let the owner know).
