Jolana, if I may suggest - if you are looking for easy Orchids which flower pretty much year around/ produce new growth year around and don't need to mature that new growth to flower - not seasonal,
here are a few:
You might find them easier under their old name though.
Ctna Why Not, (it is now called Guaritonia Why Not), will flower frequently.
Potinara Hoku Gem, (now Bc Hoku Gem) any of the cultivars like 'Freckles' or 'Sunspots' will always be in bloom somewhere on this plant.
Lc or C. Mini Purple, blooms several times through the year, same for
Lc or C Love Knot
These are nice, manageable Cattleya types, not growing out of proportions /will not right away outgrow a window sill. One thing they do need though and that is bright light.
