Nice and private place located in a residential district. The backyard is very green and private.
We stayed with kids and it was nice to be able to let them out to the backyard or take to a nearby park.
This is a good spot if you'd like to explore Seattle while working remotely. There is a basic desk, office chair, fast wifi connection. You can also opt for a coworking space - there 3 within 7 minutes of driving. Beware that lots of street in Ballard (and Seattle) are on very steep hills.
Theo and Maria were responsive while away in Europe. Colli upstairs was handling local needs and questions that we had (e.g. access to the laundry room).
The kitchen is spacious, new and well equipped.
The bed in the bedroom is comfortable. I did not like the sleeping sofa much, but kids were ok with it. It works great as a sofa though (there are two).
There is not too much natural light in the unit, however you can use the backyard and enjoy it there.
