About the buses. There is a timetable. I can't remember it exactly, but there are only 3 buses going to the parks in the morning and then the next one isn't until 4 pm. The bus starts at P&V and then picks up at Hotel L'Elysee. It can be very squashed. I had to fold up the pushchair so I could make more room for others. We stayed there at the start of July, so it wasn't high season yet. You could probably walk, but with my awful sense of direction we got lost and gave up!
The apartments were very clean, but were a bit worn. The beds were very comfortable - even the sofa beds. There is no housekeeping, but there is a vacuum cleaner provided. There is also a clothes horse, but no teatowel or washing up liquid or cloths. There were heaters on the walls but they weren't on when we were there! Towels are provided & 2 rolls of toilet roll, so if you run out you can buy more in the supermarket. There are plenty of cutlery & crockery, a fridge, a microwave, 2 ringed hob, no electric kettle, no grill, no toaster. There was always loads of hot water for showers/baths. The TV had a german cartoon channel - this did not seem to worry my daughter!
Overall I would definitely go back there, but with a new baby with us this year I wanted to be close to parks in case I have to go back to the hotel with her for naps etc or if the weather is too hot. So we decided to splash out this year!
