There are no real windows (glass) in the windows, just wooden shades. This means, that all the sounds from the street come directly in. My room was facing a restaurant, that had live music on several nights, so I couldn't block that noise in any way. One one evening they had a large party with amplifiers and DJ, so it was really loud! Luckily, it only lasted a few hours. But do bring ear plugs with you, otherwise you can't sleep.
Hotel staff is really friendly and nice.
