Fero's place is great, newly built, with state of the art amenities and perfect sleeping arrangements for a family with kids (separate day room and 2 bedrooms with doors). Distances to subway are very short, 3-4 mins walking.
The street, even though hosts a market, is not very loud and if you sleep with the window opened, it doesn't bother you in the morning. Complete silence at night, after 8-9PM.
All in all, a beautiful apartment, with everything you need to feel at home even if you travel with small kids. Easy to access, with good links to the city center.
