Location: fantastic! It's pretty central and close to many non-tourist-trap restaurants! Was about a 7-8 min walk from all major spots. If you want to take trains, it only takes around 10mins. Next street has a lot of stores for shopping.
Hygiene: amazing! It is cleaner than expected. We we're able to walk around barefoot very comfortably. 😊
Building: restaurants, bars, supermarkets are within mins of reach. The apartment is on the top floor of the building. It is a traditional building and very well kept. No noise at all. Just be mindful if you have very big luggage that going up and down can be a little challenging. It was about 3.5 floors.
Summer: We were there early summer and we didn't need to put AC on all the time. The AC was working perfectly. It is nicely cool around the living area. However It could be a little bit hot on the bed level during night because there's only a small window (but lovely!!) Above the bed. The air doesn't flow very well without AC. But in general it's not a big deal at all.
