Smallish but everything we needed for a 3 day stay with two little kids. Very convenient location close to SFO ($15 by taxi) and a short walk to a big shopping centre and BART station that brings you to San Fran city centre in 30 mins. Excellent communication from host re access. Host lives on upper floor but provided complete privacy. Lots of information in apartment about things to do etc. Great apartment for a visit to San Francisco.
