The apartment is perfectly located in walking distance from the main sightseeing spots. We've got the keys from the Hostmate agent who was on time to meet us (we've payed additional 15 Euro for this service, otherwise you have to collect the keys in the Hostmate office).
The apartment was very stylish and convenient, and we've appreciated how quiet it was there. On the downside, the room was very cold (we stayed there in October). The cleaning could use some improvement (we've encountered dirty dishes in the dishwasher and some clothing articles from the previous tenants on the floor). There was also no hand soap.
Other than that, everything we needed was at our disposal, and we enjoyed our stay. Thank you!
