We traveled to USA with an infant for 2 months, and MJ's place was our home for one of those months. This place met all our needs for several reasons:
It is truly equipped for long-term stays (all the amenities match the needs of staying in, not just passing by)
The location was the biggest sell- we didn't have a car and had easy access to grocery, train, park, playground, etc.
Like most places in DC, this is an extra unit built into the house. It is spacious, clean, has laundry in unit, and is really well lit. This makes it different than almost anything we saw.
Most importantly, this place felt like a home. When being away for so long and with a child, this was a real gift.
