We recently spent 5 nights in unit #4. It was a comfortable, but cozy stay for 4 adults and one pre-schooler. We were hoping our daughter could sleep in the loft area, but it was for kids >7 years old. Although not really functional, the loft space was an added bonus and where our daughter often wanted to read books and snuggle.
Unfortunately a group of rowdy 20-something year olds were staying in the unit above us, making the evenings a bit challenging. Alas, this is part of space sharing in an older home.
The location was prime, walking distance to some great places off the beaten path (including coffee shops, cafes, and a natural grocery store, two liquor stores, and even a $0.99 store). It was a short and inexpensive (<$6.00) to the Gaslamp area as well as to Balboa park (< $10.00). The front and back yards were a fantastic addition to the space. Laundry is always an added bonus when you have a child!
