We enjoyed staying in this apartment with our two kids this June.
As others have pointed out, the house is not probably the best choice when traveling with kids. We rented a cot from a 3rd-party service. The room is on the 5th floor but the elevator goes up to the 4th. The room has no curtains and no way to block the light from coming in at night (until 10pm on June), so it might be hard to get kids to sleep. Additionally, it can get hot in the summer and opening the windows is not always an option due to mosquitos. The air-conditioning worked good enough. None of these concerns caused us a major problem though.
Apart from the children-related concerns the apartment is very nice, well-equipped and at a very convenient location. Checkin/checkout were smooth and the communication was fast and straightforward.
