We had very nice stay in these apartaments. They very a bit better than we expected. Stylish. Not so spacious as our own home, but it was enough. I would say sound insulation was good, but in the evenings you could hear neighbours, almost could not hear the noise from the street.
Had some issues - was no heating and hot water one morning, but it was sorted out very quickly - very good communication, quick response.
Found some complimentary biscuits and drinks on our arrival, it was very nice and pleasure from our host :)
Def.would stay again and would recommend to my friends.
