My wife and I stayed here for over a week and had a great time! The place itself is a bit small with low ceilings, but has a wonderful, cozy vibe. The statues, lamps, couches... all give this studio a unique feel that you won't find anywhere else. Other reviews mentioned some potential slow internet, but that doesn't seem to be the case. We were both able to work and take video calls throughout the days without too much trouble.
The only drawback to be aware of is that the upstairs neighbors start their day on the early side, we heard footsteps, loud talking, dogs and once a vacuum before 8AM on most of the mornings during our 9 day stay.
The neighborhood is a bit sparse except for high-scale restaurants, fancy furniture and antique stores, but if you don't might a bit of a walk, there's some bars, coffee shops, and cheaper fare within several blocks. It's very close to the Presidio, so plan on walking up on through it while you're here!
Springer is a very attentive host and will reach out to make sure you have everything you need! Happily giving this place 5 greek statues out of 5!
