Location - This place is in the heart of town. 10/10 for location. It's 2-3 mins walking from Old Town Square.
Check in - was super straight forward. We couldn't find the key to the building initially, but a passers-by pointed to the locks attached to a pipe outside the building. Luckily I found one for me with my name on it.
The door on the 4th floor (for the keys with many numbers) also needs to be repaired. The key wouldn't turn initially and it took us almost 10-15 mins to pull the door towards us, and open it.
The apartment - it's a beautiful spacious apartment, and good enough for 2 people. It comes well equipped with kitchen appliances and has ample storage for luggage. There's also a washing machine you can use.
All apartment instructions are enatly written and there is also a folder with recommendations about what to do.
The bed is very comfortable.
The only downside in the whole listing is the Sofa-bed which is extremely hard, and is unusable. We were three of us in the apartment, and we took turns sleeping on the floor, because the sofa bed has an odd central wooden slab.
On the whole - I loved my stay here. The apartment is very central, comes well equipped, has a good view, and has everything you need for a good stay. Would highly recommend it, and would be sure to come back. :)
