This was a very spacious and comfortable apartment. Everything we needed was there. We bought a European converter plug, only to realise later that there was one in the flat already.
We enjoyed the neighbourhood. It was quiet and walking distance from the metro underground. We even walked with our luggage from the Bart station when we arrived (and when we left). The pavements are broad and quiet enough to trolley your suitcase behind you.
We preferred the restaurants in the Mission district to those in Union Square (thanks for the tip, Todd). They were a close 10min walk from the flat.
I would seriously recommend this aparment to friends or anyone that prefers a quieter, yet interesting, neighbourhood while visiting San Francisco.
Thanks for having us, Todd and Amy
