My 2 kids and I stayed at Lyle's apartment for 3 nights on our sight seeing trip to D.C. in the middle of July. A comfortable apartment, reasonable Uber rates to and from the Mall and surroundings. Easy walk to the Metro (about a mile), it is a downhill walk to Dipont Circle. So it was ok with a 7 yo (and an 11 yo) in July.
The walk to Safeway was a bit longer than we anticipated. With groceries we took Uber back.
Clean, and had everything we needed for a comfortable stay.
Lyle was very helpful and responded to our questions via airbnb and text pretty much immediately.
We would definitely stay there again!
