We thoroughly enjoyed our stay at Dan's apartment. The apartment is in a very convenient part of town with two subway stops within a couple blocks. It is close to shops, but also outfitted with a full kitchen and laundry. Dan sends you this great pdf 'manual' with all kinds of useful information that helps you prep before arriving. The place itself is very nice. Everything is well kept and tidy. Dan has a maid that seems very willing to help out. I believe she comes every other day or so. We were so well taken care of, we didn't need much support, but it's nice to know she's there. Dan was very kind to change his schedule and personally let us in when we arrived late. The apartment is very unique and in a building that expects restraint and quiet. Dan is clear on that requirement. As guests, it was harder to keep my gang as quiet as I'd have liked. If you have a loud family like ours, make sure you set some guidelines with the kids.
The final point is that the apartment is on the fifth floor. We loved walking up the stairs (quietly), but it also has a pretty slow elevator that is perfectly sized for a romantic couple. Again, I couldn't recommend the place any higher. With nice views of the Eiffel Tower from two rooms and so close to the metro, it provides a great base to explore from.
