Hi Sheila, thanks for staying in our apartment!
That's the first time we got any comment about the smell in the building and inside the apartment. We will definetly be careful about the smell in the apartment but as you noticed the living room as a big door directly to the balcony and during summer it's most of the time open. For the building, as you said, it's a old apartment in a old building with wood floor everywhere and may be (I think!) wood smell.
I'm really surprised that's the dishwasher was not working, it's a new washing machine and when I get back to the apartment a few days after your stay, I used it, and guests after you still not mention anything. If it was, sorry about that!
There's not many space but it's a good idea for the little table in the balcony!
Regarding the sofa, actually I already planned to change it but order and delivery it's a little bit long. So you right, it can be much better!
