I don't think we could have found better for our 1 month stay in SF, for my partner and I.
As slow-travel digital nomads, this place was perfect for every of our needs:
Check-in was easy and the apartment was clean.
About the stay: First, the apartment is huge, with practically two living rooms, meaning that we could have our work setup on one side - there was even a desk with two big screens and a confortable chair - and "chill" setup on the other side. WiFi was very good for both work and entertainment.
The bedroom is also quite big and the bed is comfortable. It is located more on the "back" side of the apartment instead of the main street, which made it very quiet during the night - except when the trash truck was around.
The kitchen was well furnished which was very welcome too as we like to cook. The was also a bean grinder and programmable coffee machine - perfect for me as I am not a morning person.
Now for the location:
Extremely well centered. Walking 10 min can get you to Fillmore street, Japan Town, Polk Street, Lafayette Park or a Trader Joe depending on the direction you go. Also walking 30 mins gets you anywhere interesting in SF really: The sea, Presidio, the center, China Town, Mission District, etc... which was perfect for us as we love walking and simply had the embarrass of the choice whenever going out.
Giancarlo was extremely reactive to our questions during the length of the stay (a few minutes) which was very useful too.
Nice bonuses were the laundry machine + dryer at the bottom of the building (takes quarters), the big TV with lots of VOD options and the mini-balcony.
TL;DR: As a couple staying there for both work and tourism, we were totally spoiled there and got everything we needed for our 1 month stay in SF
