Claude was a great host - very quick at responding, explaining, helpful, friendly and flexible.
As explained, the apartment is a studio - one room with a bathroom. As someone else has explained, it's on the fourth floor with no elevator. The bed was a 'flip-down' sofa bed tucked between the tv unit and furniture. The tv unit took up most of the back wall, so natural light is limited. There is a lot of artwork and furniture in the apartment, so floor space is limited. There is no closet space. The bathroom has a 3/4-sized bath and powerful shower.
The area is full of great looking restaurants and bars - buzzing and safe. It took me about 20 minutes to walk to Central Park. The subway is a short walk away.
