Pros:
Location
The unit was very clean
Kitchen is well stocked
Walking distance to a few restaurants
Parking spot in a garage is a real bonus in San Diego.
Fred/Property Manager was very responsive
The bedrooms were a nice size and the we found the mattress very comfortable
The bathrooms are small but nice (but be forewarned the bathroom on the main level has an etched glass door that can be seen through. Privacy can be achieved by closing the bedroom door).
Cons:
This is depicted accurately in the description but I want to note -- there is no elevator and the stairway is tight. Be prepared if you have heavy luggage to walk up a flight of stairs.
There is no AC (also noted) and the place gets stuffy without the windows open. We stayed in May so didn't need the AC but I can see that being an issue in the summer because it's noisy on Pacific Beach and if you needed to keep the windows open you would hear all the night and morning sounds.
This unit is best for 2 people (maybe 4 adults max). The unit is lovely but it is very tight (it's a narrow design) so when the listing details note more than the max 6 people are in the unit, you will lose your damage deposit" - it's because the place is so tight. The kitchen especially is where you can't have more than 1 person on each side of the kitchen "island".
I would not recommend this place for small children. Again because it's tight - on the main floor children would have no place to move around. And also because the floors are all tile (even the stairs) which could be challenging for small children and if they fell is a hard fall.
The twin beds are described accurately - they are very tiny and only for small children. Especially the top bunk a child would easily bump their head with low clearance.
The reason I gave this a 4 instead of a 5 was because there was a full blown graduation party on the patio during a day of our stay. Fred was very responsive in addressing the situation but it also prevented us from using the patio for 1 day of our stay and we had to walk through the party every time we went in and out of the unit. I was very surprised by this because there were so many rules in renting this unit of which we were very respectful of.
