My family of three recently stayed here, and had a mostly positive experience. I would like to first point out the positives: the flat was clean upon arrival, and it provided the necessary amenities for a prolonged stay. There are two smart TVs for use, as well as decent wifi. It is conveniently located between an underground tube station and Sainsbury Market for supplies. The City Relay representative Matilde was very cordial and a pleasure to deal with.
For the not so great: this flat is located on the third floor, with no lift access. This proved be very difficult traveling with a toddler and asthmatic; so please be mindful of your requirements. The property was very warm and humid through most of the day, with a single weak floor fan as the only source of cooling. Though it likely would not have remedied the ventilation issue, the window in the kitchen did not function, so when using the cooktop the flat was heated even more. The shower valves leave much to be desired. The water temperature was not only difficult to dial in, but it fluctuated constantly. The best method I found was to turn the hot water all the way on, then micro-adjust with the cold (this cold water is hypersensitive.) The bedroom has very little storage for clothing; there is one black cloth hanging caddy and three wood hangers. Lastly, the outside noise was a huge issue, constant sirens and pub-goers walking by prevented quite a bit of sleep. This is not the fault of the property, but it should be noted for those that might find this bothersome.
I will say this property would do nicely for those traveling without children, and you will appreciate the close proximity to the public transit. Families with small children and/or health issues - while the listing is certainly doable, we find it difficult to recommend this flat. We would be searching for a listing in a quieter area, with better access for families. I hope this information proves useful to someone, and would like to wish you safe travels!
