My boyfriend and I stayed here for a weekend and had a wonderful stay at Ven's suite. Ven was great host and super responsive - he provided us with all the information we needed at least a week in advance for checking in and responded to emails within 15 minutes.
If you're looking for a secluded place to stay, Santa Monica is a great and convenient choice, and I highly recommended Ven's suite for couples who are not looking for anymore more than a comfortable place to sleep. There are lots of restaurants in the area as well as supermarkets and 24-hour pharmacies for your needs. It's also a 15-20 minute drive from LAX without traffic.
The space is a guest room and bathroom in a larger house on a quiet residential block with a separate entrance and gate so you don't lose any privacy. There is ample street parking and a parking pass for street parking for specific hours is available for your use (but we didn't need during our stay).
I really liked the bathroom - it was extremely clean and felt pretty new, and the shower was big with a decent shower head and great water pressure. The bed, which was a little on the softer side, but comfortable nonetheless, came with memory foam pillows which were a welcome change to many airbnbs that I've stayed at with flat mushy pillows. I was also pleased that there were also standard pillows that are softer for people who don't like memory foam - it's rare that you are given an option! Other features include lots of closet space, a mini fridge, and a microwave, but we only took advantage of the fridge for water.
I had no complaints about the guest suite and I would definitely stay here again if I find myself back in LA.
