Michelle and Mary's place is very nice. The bed is comfortable, the space is modern and charming, and very clean (okay, they do need to clean under the bed a bit better. A bit too much dust there for my taste). The space is large--much larger than a room in a high-quality hotel that would go for $250/night or more. They do go a bit overboard with the (ammonia-based?) cleaner. Hopefully, they will find a happy medium.
Location is good. Very close to downtown. We got to the Civic Theater by Lyft in five minutes and to the S.D. Zoo by car in 10 min. The neighborhood is transitioning with lots of homeless people (I guess that's quite common for a warm-weather urban center). However, it seems to be quite safe. There are two codes to get to the key to the unit. The first code is based on your personal information (fine). However, the second code with the key to the unit was rather predictable. Hopefully, Michelle changes up the 2nd code often, otherwise I worry that it might be too predictable.
Overall, our experience was excellent and a great choice for a S.D. visit. Michelle puts a lot of care into this unit, and it shows. I would definitely consider staying here on my next visit to S.D.
