Matias's place is a lovely house located next to a beautiful lake around 20 minutes drive outside from the city centre. (But as Matias says, public transport is convenient, so there is no need to drive into the city.)
The lakeside itself has a playground just across the road but our kids loved playing in the house itself with the toy kitchen!
The house is beautifully set and completely safe for kids. We can see Matias has a young daughter and the house is adapted for her. Only caution for very young kids is that the staircases up and downstairs are quite steep, but our toddler was sensible about these.
Matias was always on hand at the end of a phone/message to help us when needed (such as when we couldn't work out how to unlock the hobs when the child lock came on!).
All in all, we always looked forward to coming home at the end of each day. Thanks for the lovely stay!
