The *location* is very good. It is walking distance from many restaurants and shops and and a less than 5 minute walk to the lake. It is in a central area so you can easily travel by foot. There is public transport (train and buses and taxies) nearby if you need to get further.
The apartment is better suited for a group no bigger than 4- ideally a couple with 2 children. There is not enough room for 5 adults as there is only 1 full bathroom making mornings particularly hard to manage in a group. The space is a converted office and the main bedroom and lounge area are in 1 room with a glass wall and door separating it from the common area. This doesn’t provide a lot of privacy which is why it could be uncomfortable for a group of adults.
