Josef and his staff are pros. They are responsive, courteous, and sincere. The place is run professionally and it shows. The apartment is honestly much better and bigger than the photos. The space was clean, stylish, inviting and warm with lots of green plants, good WiFi, comfortable table and couch to work, and good water pressure in the overhead shower. I was there on a work trip and it was perfect for that. The coffee and tea they provided was delicious too.
The location is very central but it is the middle of some of the most popular tourist attractions so make sure to get reservations for dinner ahead of time.
If you eat meat, there is an artisanal butcher shop at the entrance of the building which seemed super popular.
If you swim, there is a functional / no-frills pool and sauna (Axa) within walking distance that you can pay a modest fee to use.
They also stored my luggage for me after I checked out which was very kind and convenient. All in all, very accommodating and responsive crew.
