You couldn't stay in a better location in Old Town. The street is a dead ringer for Diagon Alley in Harry Potter. The street noise didn't bother us at all, there are double windows, but there was an occasional group of singing people who walked out of bars late at night. If you have kids that this might bother, then ask for a room that isn't right on the street - there are several units in this extremely conveniently located building. There's also a phone that they provide for you to use for free too while you're in Prague. Nowhere in the Airbnb material did I see this mentioned and it was really handy! This is one of the prettiest places to stay in the heart of Old Town and is managed by a very professional group. It includes daily cleaning which we didn't expect, so it really is more of a hotel than an apartment. The Trdlo across the street has the best ice cream, coffee, and breakfast rolls that we found in all of Prague. Our teenager had to have one each day we stayed. If you're deciding between this spot and any others, choose this one.
