Portsmouth accommodation choices - help?!

I went to the offer day, made it my firm, but didn't see any of the halls so I'm choosing from online info only and it's hard to know what they're actually like!

Going for self-catered halls, I've narrowed it down to 4 on the basis that they all have ensuites and 3/4 beds. (I'm lucky that I don't have to worry about cost as they're all cheaper than the halls my siblings were in at different unis.) So how do I choose between:
# Catherine House (135-145pw)
- seen the 'Skylounge' online, looks good
# Margaret Rule (138pw)
- older but refurbished?
# Chaucer (148pw)
- brand new, but only 2 pics online to go by!
# Greetham Street (148-154pw)
- gather it's newer, has a good communal space?, but more expensive

Grateful for any help you can give me!

Hello! Hannah from the Student Housing team here! We have got an Open Day on this Saturday if you have the time and you can come and do the halls tours which might help with the decision making process!

I saw that but can't make it, we live in Bristol and I'm doing an abseil for a charity fundraiser! If we came down some other time, would we be able to look around the halls at all?

Is there any other information you can give me? Do they all have common rooms? Which have bigger rooms? Do they all still have spaces?
