If you are tall or large then you may find it a bit tight so do try it out with a sleeping bag and mat before plonking down your dollars. Similarly the height of the inner above the floor is 60cm or less if there is any sag in the inner - so < 30 cm from your face when sleeping. I always consider the width 30cm above the floor as this is a minimum height that my mat, quilt and body will fit under. When you do the trigonometry on the design you will find that only 1.7 m of the total length has 60 cm or more width at floor level and this decreases quite quickly as you move above ground level and away from the centre.
My take is that in rain the inner will get wet every time you open the door and the tent has to be very long because of the pointed ends to get adequate width. The design is quite good and requires minimal pegs and is a reasonable weight for the price. The Spartan is a copy of a model offered by one of the US UL gear manufacturers - I can't immediately think of their name - and I seem to have seen it elsewhere.
