Built in 2011, the Hotel Grums feels more modern than many other four-pearl properties in Barcelona. Sleek decor in mainly white and neutral tones dominates the design in the guest rooms, giving them a cool, fresh look. The lobby has a bit of a warmer vibe, with luxe details that include velvet armchairs in shades of red, brown, and black arranged on a plush rug. Shiny marble floors and elegant lighting fixtures with a modern twist make for a romantic, edgy feel throughout the hotel's public spaces.

While it's not central to the hustle and bustle of Barcelona, the Hotel Grums is a good choice for those looking for something modern and quiet. Located in the mostly residential neighborhood of Poble Sec, guests will find it gets quiet come nighttime, which is great for sleeping but not so good for finding a spot to grab a late-night snack. Situated at the base of Montjuic and just a few hundred yards from the port of Barcelona, there are a few bars and restaurants nearby, but the selection is more limited than what's found in the city center. The Parallel Metro Station is a 7- to 10-minute walk from the hotel and Las Ramblas is about 10 to 15 minutes away by foot. Some guests have complained that the area immediately surrounding the hotel is a bit rundown and feels unsafe.

If there was one word to describe the 78 rooms at the Grums Hotel, it would be white: White cabinets, white linens, and big white headboards. There are also light wood floors and beige walls. The decor makes for a fresh, clean, and modern feeling. And all those neutrals make the occasional pops of color -- like purple throw blankets -- really stand out. There are five room categories, with the most luxurious featuring spacious, private sun terraces. The other rooms have floor-to-ceiling windows, hairdryers, mini-fridges, and flat-screen TVs. All come with free Wi-Fi as well.

One of the most popular amenities at Hotel Grums is the spa and wellness center, which makes for a great relaxation spot. It features a water circuit with a whirlpool, waterfall, jets, steam bath, and Finnish sauna, complete with an adjacent ice fountain. There's also a small fitness center and a daily breakfast buffet. Grum's restaurant serves Mediterranean food nightly and the cocktail lounge prides itself on its gin creations. There are a couple of computers and printer available for guest use, as well as free Wi-Fi throughout the hotel.
