We stayed 3 nights in the apartment a small family with 1 kid of 1,5 years.
Mireria is very nice and helpful and answers fast and helped out a lot in terms of staying with a kid, but the apartment is low value for money in our opinion. It wasn't cleaned very well and it is structured very badly. It's neither a place where you want to eat or cook or stay for very much time. It's badly ventilated, especially the toilet which you can only enter through one of the bedrooms. And it gets really noisy allthrough the weekend nights. And believe us, we live right in the middle of a European capital and are used to noise, but this apartment complex is basically the upstairs of a festival area.
Of course this also means that it's close to everything, which is nice.
