We had four primary criteria when looking for a place to stay in Oxford: Price was admittedly first on the list, second was free on-site parking for the car, third was access to busses into the city; fourth was breakfast included in the price. The Tree Hotel delivered on all of these plus a few more. However, it is really just one step above a hostel (which was fine for us) but would be disappointing for someone looking for refined comfort.
Key pluses: the hotel and area felt safe. We never worried for our car or felt uncomfortable walking through the neighbourhood. Iffley looks and feels like the quaint English village is us.
The Bangladeshi-Indian restaurant. This is the one area of the building that looks and feels well kept. It is bright, clean and clean--important for a restaurant. The "Kurma" is excellent, and the "Patia" ... we had to go back a second night so I could have it again. I wish they bottled it!
The room was tidied every day with bottled water and T&C replenished.
The negatives: it is a hotel very much in need of a handyman to look after loose and missing fittings, mouldings, carpentry, plumbing etc.
The staff were a mixed bag. Some were excellent and very helpful and accommodating, others not so much. Some left you feeling that the primary focus was about controlling costs (OK, fair enough).
Takeaway: We would stay again.
