Super Seven
Notre-Dame Cathedral
The Notre-Dame Cathedral is in the centre of Luxembourg City and one of the main stand out attractions, as well as being the only cathedral in the entirety of Luxembourg. It was originally built in 1613 and is a great example of late Gothic architecture. At the cemetery of the cathedral is the National Monument to the Resistance and to the Deportation. The centerpiece of the monument is the famous bronze monument by the 20th-century Luxembourgish sculptor Lucien Wercollier called The Political Prisoner.
Echternach
The second city which can easily be reached in 45 minutes via the many buses from the capital.
Place Du Marche is the main central square and a great starting point to explore the city. The Abbey of Echternach, City Hall, and the Column of Justice are some of the main highlights, but don't expect too much. Walk the cobbled streets, drink coffee, eat in a local bakery, and enjoy the chilled vibe.
MUDAM Museum of Modern Art
Mudam is a Modert Art Museum in Luxembourg City and is located on the site of the old Fort Thüngen. Some of the fort characteristics are still visible, so it's a great contrast between old and new, as the museum is a glass panel design. The building cost $100 million USD in construction and was opened in 2006 by Grand Duke Jean. Inside is very "minimalist" as most modern art galleries are these days, with the collections set out across three floors.
Pfaffenthal Panoramic Elevator
For fantastic panoramic views, I'd recommend Pfaffenthal Lift, which is public elevator designed to connect the different quarters of the city. It opened in 2016 and offers picturesque views of Alzette River valley below. Great engineering and a "tourist attraction" that's free of charge. For me, the hardest part was locating the entrance of the elevator, but I found a friendly local who told me to use the GPS locator of "Fondation Pescatore Retirement Home" which worked well, as the elevator is located within the park there.
Admire the Architecture
Due to Luxembourg becoming a popular financial hub, you'll come across lots of grand buildings. These are mainly Investment Banks and Financial Regulators, but if you're an architecture geek, some of them are very impressive! In the financial district you can see the Langer Banker figure, which is around 7 meters high, holding a briefcase and umbrella. Surprisingly, the best way to photograph these buildings was an open-top hop on/off bus tour.
Bock & the City Casements
The casements of the city are impressive, especially as the passages span across 21km. This is the central point of Old Luxembourg, and has been declared a UNESCO site following the amount attacks the city has survived over the decades. You're looking at a €6 entry fee to go inside the casements themselves, otherwise just admire the flower displays, bridge views, greenery, and even a skater park.
Open Top Bus Tour
Luxembourg is actually a city where it's worth doing the hop on/off bus tour. These are now on offer around the world, but generally I prefer to walk. However, I hopped on in Luxembourg on the "Red Bus Tour" and didn't regret it. Managed to cover a lot in a short period of time and enjoyed the commentary giving explanations of the buildings. The bus stops at majority of the main attractions too, and a bus passes by every 20 minutes, so you can plan accordingly.
Accommodation Advice
Accommodation isn't the cheapest in Luxembourg either. The best I could find was Grand Hotel Cravat, based location and budget at around 100 Euro a night. The hotel is directly in the centre of the city within easy walking distance of both the old town and casements. The rooms are basic, but spacious, and there's high-speed internet capable to remote work. The best rate I got was actually direct on their site https://www.hotelcravat.lu/en
Food Factor
Firstly, bring your loaded wallet. I found food options very expensive in Luxembourg. There seemed to be no "middle ground". Either pay 20 Euro for a basic sandwich snack, or go to a high-end dining venue.
If you're a sushi fan, then Aka Cite was superb! Definitely not cheap, but hard not to recommend, given the quality on offer. Here's the link to their site https://aka.lu/
Good Guide
You definitely don't need to hire a guide in Luxembourg. It's a very compact country with many tourist attractions within walking distance. In addition, all public buses are free, making it easy to reach Echternach and other nearby cities. There's a free walking tour that depart twice-daily from the centre of Luxembourg City that's worthwhile. The link to the info is here.
