Overall a good and decent place, but is at a fairly inconvenient location, especially if you do not have your own mode of transportation. BART station is a mile away (which is a very long walk). They do have convenient bus stop locations, but bus frequencies are spread out and they take a long time to get to your destination (for example, 45 minutes bus ride to go to Berkeley campus - which is less than 4 miles). So lots of Uber rides (which add up fast)
Would definitely give it 3.5 starts.
Add 50% extra to the advertised rates (to account for Service Charge, Cleaning Fees and the exorbitant Local Taxes) for a 4-5 day stay.
