We had lovely time at Mauro's place. Despite the fact that he was sadly out of Prague during our stay, his PA Daisy was more than accommodating and really responsive.
The flat itself is simply amazing, pictures give it justice, being located near the river made the experience even nicer.
All in all, it was a pleasant stay and would recommend the stay here for sure.
The only downside is perhaps the disposal of garbage - it seems that garbage bins are locked and only accessible if u have a key, so we needed to left the trash on the street.
