It was a pleasure staying at Albertinos apartment with in total 11 people - apart from the great communication beforehand, while we were there, he always (literally 24hrs) helped us out fast with good tips and extra services! The grocery is also very close, and it's super easy to either walk to the city center, take an uber, the metro or a cable car. For a trip with many people (up to 14) I would definitely recommend this apartment! :)
