I like this particular H&M store even though a lot of their clothes are all over the place. There is only a handful of people working there, but I don't mind. I actually prefer it that way rather than having someone asking me "how do you find everything today" just upon entering cause they are bored. The clothes are usually good quality for a reasonable price, particularly if you're looking for basics.
They don't have the biggest selection of clothes, but you'll definitely find a couple of good items.
This store is never too packed with people, so I never had to queue up for fitting rooms etc. All in all, if you know what you want and you only need basics, this is the store for you. Don't expect too much interaction with staff cause there aren't many around.
