Paris is a beautiful city. We were there for four days and we thoroughly enjoyed every bit of our stay there. We stayed in a street called Rue Cler and I think we made the right decision because it gave us a glimpse of how the Parisians live. It's not overly touristy and most importantly, it's near the iconic Eiffel Tower, which is one of the most visited places in the world. Coming back to Rue Cler, it is one of the most famous markets in the city so you can expect market-type vibe but Parisian style. There are plenty of cafes and restaurants so that you won't go hungry. Furthermore, there are two metro stations nearby with the nearest being the Ecole Militaire metro station.
The first place that most tourists go to after reaching Paris is the Eiffel Tower. Do keep in mind that there are lots of pickpockets around this area and we were specifically warned by the locals to be careful because those who steal are well- dressed and as such, you won't know that they are after your belongings. Entering the Eiffel Tower garden area is free but if you want to go up the tower you need to buy tickets for the same. There are two types of tickets to access the tower: ticket to second floor and to the summit. We bought both the tickets and the best view of the city was obviously from the summit. There are also two restaurants up the tower but reservations are required for the same. What we did was we booked the dinner at ' 58 Tour Eiffel' online and just went for the same on the specified date.
