Right in the heart of it all, Martin and Jamie have a great place that has it all for a large family. They were very responsive and accommodating with our prearranged late check-in, and even had a portable crib and high chair set up for our baby. There are stairs, but I found them relatively forgiving even with my notably bad knees. (The individual step height isn't just a bit more shallow than standard, which puts less pressure on the joint as you walk down). And I found it easy enough to rest on the 4th floor if I needed.
