The Strand Hotel in general is a wonderful place, very elegant and comfortable. We only booked breakfst which was very good overall, we didn't miss anything there. We ordered room service once, which didn't take very long and the food was amazing. I expect that everything on the menu is of high standard from what we've seen.
The room itself didn't have the best view, but the room itself was very nice, quiet, tasteful and cozy. Some dusty parts, but not so much to make a big fuss about it. Some miniscule negative details were the toilet paper, which is very very thin, almost like you can look right through it and no toilet brush.
The gynasium was mediocre, very little room to move around, a broken Smith Machine, worn down material. Big room for improvement in a 4 star hotel.
The parking situation was a little frustrating on Saturday evening. We came back from the Convention we were visiting and all the parking spaces at the hotel (7,50€ a day) were gone. We drove around for about 15 minutes to finally use a space that wasn't supposed to be a parking spot in the first place, we did, because others used that spaces too. Seems like some people that are going out in the city are using the place for parking as well.
Highly recommend booking a room with view on the river, we would definately do the next time.
