We had a lovely stay at Jaya's Annex. It was comfortable and pretty spacious as studio spaces go.
The location was really good if you want to be adjacent to the city without needing to be bang in the centre of it. We had a rental car but when we didn't feel like driving into the city it was very easy to get there on the bus. The stop is only a five minute walk away, the bus is regular, and it brought us to Temple Meads in around 10 minutes.
Our hosts were very nice too, and very quick to respond to communications. Check in was hassle free, with the key to the annex in a safe outside, the code for which we were sent when we touched down in Bristol. This suited us perfectly as we had a loose agenda and didn't know when we'd be ready to check in.
Overall very nice stay, and I wouldn't hesitate to stay again.
