We stayed at Viviana's place for 1 night whit our 11month old son and slept very well.
Checkin was easy and also Viviana welcomed us, as we just met her on arrival.
The apartment is perfect for a short stay and we even got some toys to keep our little one entertained.
As mentioned in other reviews, you can hear the noise from the top apartment very well. Every step, every cabel pushed in or pulled out, every drawer, even the TV. Same again early in the morning. This wouldn't have bothered us, but made it very hard to put our baby to bed.
Other than that, everything was sparkling clean and we had everything we needed.
Very much recommend if you don't mind the noise. :)
