The concept of SweetInn is great, it's a hybrid between staying at a hotel and renting someone else's apartment, unfortunately, the execution isn't quite there. The host was almost an hour late in meeting us (not fun when you're traveling with a 1 1/2 year old). Through Airbnb, during the booking process, we had requested a crib for our baby to sleep in (listed on the available amenities) but none was there when we checked in and it took hours to get one which means our baby missed her nap and was cranky all afternoon. The listing said that coffee would be provided and we looked forward to having a relaxed cup of coffee at the apartment before starting our day but there were no nespresso capsules to be found, we were told some would arrive with the crib later that afternoon, then we were told they would instead bring some the next day but in the end, they never arrived. We were given 2 sets of keys to the apartment which was great since there were 3 of us, luckily we tested the key right before leaving and realized only one of them fit the lock! We were told the correct key would be brought later that day but instead, a duplicate of the key that didn't work was delivered. Again, the concept is great and maybe they'll get their act together but right now, the process is a bit of a mess as you're dealing with different people rather than one contact person. We had stayed at a private apartment the previous week and the experience was much smoother.
As for the apartment, the location is great though quite loud at night!
