Great, central location. Good bakeries and supermarkets nearby, and a 2-minute walk from bus stops and a subway station, from where it's easy to connect to any of the major train stations or the airport.
Easy self-checkin using a.lockbox, so we didn't have to worry about arriving at a certain time.
The wifi connection was fast and reliable, we were able to join video meetings that we had during our stay.
High-tech blinds in the apartment that can make it really dark during the day in case you want to sleep in or nap.
