Claude's place is really close to times square as advertised. There are many metro stations in the area that take you pretty much where you want to go within a few blocks from the apartment. It's in an older building, the place is not huge (suitable for 2 people and a child), but it's really all you need. Claude works pretty much all day and night until midnight usually. He made us breakfast for the morning before he slept, nothing fancy but it's a great little perk that made us feel at home. We arrived past 1AM and he was up to let us into the apartment! And when we left, we had a late afternoon flight and he said no problem to leave our bags there until we needed to leave. Great hospitality, great host, great everything. This place is a steal for the location!
PS if you stay in the winter, as we did, the building controls the heat so the place will be very toasty. Luckily you can open the window to let in some cold air to even it out.
