The apartment is in a very good location, all the rooms meet the fotos on the publication. A lot of amenities like towels, soap, washing machine/dryer and some goodies in the kitchen are appreciated. The only downside is the one very small room, if you are only 4 people you do not have to use it, then it's fine. Otherwise bear in mind that you have to leave the door open (although there is aircondition) because there is no window and no space whatsoever and you feel claustrophobic.
Check-in/check-out is very easy, the location very good.
