Stayed here for a week in July 2018. Family of four, with a 2yr old and 12yr old. It was ideal for both. We had no.6 ground floor apartment, which was just next to the pool and across from the playground.
Our apartment was spotless and very spacious. We could tell parts of it had recently been done up. Both bedrooms had loads of space. The living room also had couches (which I think was a sofa bed too), chairs, din din table. The kitchen is well equipt with cooker, microwave, utensil, fridge, freezer etc.
If you're looking for a place to chill for a week PMV is ideal. There's a restaurant across the road that does takeaway, which was ideal as we arrived in late and could get some food. There's a garage next door, so you can get water, snacks and beer/wine there. There's a supermarket and some shops/cafes about a 5-10min walk down the road where's you can nip out to get lunch. The apartments have a little cafe/bar where you can get snacks, drinks etc and it's not too expensive.
It's about 10mins in a taxi to Old town. Using the local taxi service for us it cost 12euro flat fee every time. Coming back from the old town, using regular cabs the fare was about 9euro.
However the local taxi service are great if you need car seats for kids, which the town taxis don't have. Just let them know you need a car seat and they were always able to provide one. They will come and get you from old town if you cll them for the same price. And are very reliable. Never had to wait more than 10-15mins.
We also went to Aqualand water park on a Saturday. It was great, cheaper than the rest, suitable for small children and young teens. Didn't have to queue for anything really. Lots of bed and shade available. Lots of lifeguards. The restaurant in it is the most expensive thing we've seen. 13e for a burger and chips so I'd recommend bringing your own snacks if going fr the day.
