If you're reading reviews stop here - 20 Seaton is an amazing place, we stayed for 5 days. After a day of sightseeing, to come "home" to such comfort and rooms to spread out in, was wonderful. The furniture, beds, decor, huge kitchen area, were worth the investment and so glad we chose this place to stay.
The neighborhood is so quaint, residential, with restaurants around the corner. Highly recommend Aroi, a Thai/sushi restaurant very reasonably priced. And a tiny market for your food/wine runs. At first I thought we'd be far from the sights, but most were within a 10 minute Uber ride.
