Unfortunately during my stay there, we found cockroaches in the shared kitchen on the first floor crawling around on the floors and sink. This is a health and safety issue that needs to be resolved and should be checked on consistently afterwards by the host.
I was visiting Cambridge and decided to book John's listing for two nights because of the price and location. In hindsight, not worth the headache and issues which sprung up during the stay. This entire house is rented out to college students, because there are multiple bedrooms on each floor. This room is an attic suite (not mentioned in the listing itself).
The avg. temps were around 100F (38C) in the city at the time of my stay. Unfortunately the air conditioner that was advertised in the listing was old and barely working when I got there (all it did was circulate warm air). As this is an attic suite, all the heat stayed in that room and there was very poor air circulation.
The room is very small and has low ceilings, additionally the door is a little wobbly and needs to be shoved in order to fully close it. The room is very bare-bones, and there was some open wall trimming along the floors that exposed very old and rusty pipes which was concerning that they were not covered away.
All that said John is very responsive. When I told him about the issues I encountered, the very next day he got his assistant to try and fix the cockroach problem and replace our air conditioning unit. I can only hope that the rusty pipes issue can be resolved soon as well for other tenants. He mentioned that this was the first time someone had complained about the cockroach issue, but I'm a little concerned for the other residents in the house, many of whom stay long-term because it is so close to the colleges. It's a convenient neighbourhood, but I would double check these issues are resolved before booking a stay here.
