The location is great, nice neighbourhood with good restaurants, easy to access most tourist things.
The noise tho is intense, from constant street noise to other guests in the shared hallway at all hours, and the office attached to the apartment.
if you're used to noise, it's most likely no worry, bit if not it can seem like there's actually no walls, especially on the weekend.
WiFi worked well
Beds ok
Good sized space
The communal balcony is interesting, as anybody from the building can just walk around it's a bit awkward when your laying in bed and a random person passes by the window ;)
It's very secure, and the door guys are great.
No heating or cooling, so was fairly cold in January.
All in all good vale and good location, concerning access and neighbourhood.
