Positives: convenient location, short walk to the louvre, supermarket nearby, restaurants downstairs. Apartment newly renovated hence modern and clean even though building is old. Had problems with the wifi log in but Katarina replied my text promptly even though it was past midnight.
Negatives: Upon booking, i was messaged by Alex to email Katarina our arrival times. The day before our arrival, i still hadn't heard back from Katarina so I messaged Alex and emailed Katarina again. Katarina replied saying that she would meet us at 10pm. when we got there at 10pm, she wasn't there and had to wait nearly an hour for her and some people in my group were getting impatient. Washing machine was a bit mouldy in the detergent compartment. We were told check out was 12pm but a cleaner showed up at 915am on the day of our checkout. Wasnt a problem but communication could be better.
Tips for future guests: newly painted so had paint smell. Wasnt a problem for me but might be for you if you are sensitive to the smell. Need to carry luggage up 2 flights of old stairs. Restaurants downstairs can be noisy, windows are pretty soundproof but if you are a light sleeper, you might want to bring earplugs. One person in my group found it dusty as it triggered her allergies but i didn't think it was dusty.
