We had an amazing time at Yosemite West.
Location: Phenomenal. The home is actually inside the park, so you're not spending 30/60/90 minutes in your car waiting to drive in every day. You just get up and go. Plus, the house itself is 20-40 minutes away from most locations, including Mariposa Grove, Yosemite Valley, and Glacier Point.
The location is reason enough to stay here, but the house is so lovely and cozy as well. It has 2 primary bedrooms on either side of the house, both with their own bath, which made it perfect for us staying with another couple. The downstairs and deck have great views and are so comfortable. We cooked for ourselves the whole week and the kitchen had all the tools we needed!
The host Lori was super communicative and always available whenever we needed her!
The only "downsides" I would note, which are also listed in the listing, are not really all that bad. One is that the cell service is very minimal, but it's not available in Yosemite, either, so that doesn't really count! The Wifi worked well enough for us to be on social media, text, and browse the internet. We planned ahead and downloaded movies to play via a HDMI cable from our laptop to the TV.
As for the stairs, there are a lot of them as the listing says BUT, they are extremely well constructed. They are cement and have a railing the whole way up. One person in our group was traveling with a cane and kept remarking on how thankful they were for the hand rail. It was a nice surprise!
