We were here for 5 nights. Great check in/check out, no issues and fast responses.
The location is very good - slightly north of the city centre but great neighbourhood and easy to walk around. Bus stop right outside the door and a metro stop a few blocks away. Grocery store across the street.
Apartment itself was fine - nothing fancy but suitable for our needs. Our only problem was that there were a lot of little ants everywhere, which we have let the host know about.
