The apartment is in a perfect location: downtown, close to the subway and many tourist attractions. For those who have problems sleeping, it can be quite noisy because of the tram, but this compromise is natural, when you are in the historic center.
It can be perfect for 2 couples who have a child each. However, for us it was challenging to stay there for almost 2 weeks.
Two bedrooms have windows facing the street, so the windows can only be open during the day, due to the noise. The third bedroom has a window to the rear of the building.
We couldn't open the window even once because of the rotten fish smell. And the owner said he couldn't do anything, that's it. In that space between the buildings there were many buckets and even a refrigerator. The noise from the fridge was acceptable, especially since it doesn't run 24/7. Instead, the smell was terrible.
We were away for about 12-14 hours every day and we left the windows from the street open + all the doors in the apartment opened to have breathable air during the night. And I think the mattresses haven't been changed for a while.
it's a great place, with a lot of potential, just need a little extra care.
