If you want a cheap place to stay then this may be perfect for you. It is much less than other things offered in Bristol so if your driving factor is price then I would say this could be the place for you. Easy to access and has the basics needed for an overnight stay.
Things you might want to consider though if, like me, safety and being comfortable is important to you. You are in an annex in the back garden that you get to through a gate down the side of the building. In the garden, where the annex is, you are sharing an access point with next doors garden too. The annex door does not close properly, although the host did say they would fix this and offer to lock the gate (I was worried about getting out and mosquitoes so declined this) - but I note it is an issue outstanding since a review in March.
The decor is much more rundown than shown in the photos; blinds rusty; one does not pull up. There is a load of foam filler in the bathroom and the hot water is very hot - beware! The road outside is quite busy and the area does not feel very salubrious. I would recommend ear plugs and an eye patch for sleeping - due to the blinds.
I stayed one night - I would not return and am glad it was no longer. However if you just need somewhere to rest your head with somewhere to cook and shower then this might be just the biscuit for you - I have suggested to the host some updates, which if they do address may improve your experience.
