This is a great apartment. It is genuinely lovely and spacious. It has clearly been kept in good condition. The communication prior was very good and I was even provided restaurant tips prior to my arrival. It is not right in the centre of Manchester but it is a small enough city that it is not a long walk either. There were some lovely touches in the apartment as well - the provision of shampoo in little bottles and the little breakfast cereal boxes with milk. For other things some of the care staples are there - tea, coffee, ketchup, etc.
The only downside is that Sackville street can be quite busy, particularly on a Saturday night. I was woken several times including 3:30 in the morning by a dad yelling at his 8 year old song to come home and get into the house. Having lived in Manchester previously that didn't greatly surprise me.
Apart from that one small thing it is a really great apartment and I would highly recommend it.
