Frank's place is good for a short stay in Manchester. It's 20 minutes from the city centre by bus and opposite a Tesco express, which makes it very convenient.
Frank is also a lovely guy who was very amenable and helpful during communication prior to our visit, and handing the house over to us, so I can't fault him for anything there.
The only issues we had with the house was that there are several rooms which you can't access which makes the place feel a bit unwelcoming, and also you can't access the garden as there is a couple living there in a caravan. They seemed like nice people and didn't bother us at all during our stay, but I feel like this is something that should be mentioned on the listing as most of the accessible rooms look in on their caravan.
The cleaning also left something to be desired a little bit, as we found some items from the previous airbnb customers and some areas were slightly dusty. The house is rather large, though, and while I don't think it was unclean at all, I think the wear and tear that it shows made it look that way a little.
Overall, it was a fine stay for the one night we were there and is perfectly good for a night's sleep if you're looking for somewhere to stay in Manchester, especially for the price listed, but I would say it is lacking the extra touches which make it feel like holiday accommodation.
