Gareth's place was exactly what I needed for a few days in London. I was landing late at LHR so proximity to Paddington and the self check-in were important. The place is also very close to the Bakerloo line (Queen's Park) which was perfect for the things I had to do in town. Also close were Alice House for a quick drink when I landed and Gail's bakery for coffee and treats in the morning. (Or if you prefer, the Starbucks another block away.)
Soap, shampoo, washing up liquid (dish detergent), etc., were all supplied in convenient plastic pouches. Towels were supplied, too.
The studio apartment area was big enough for one person or a couple that wasn't going to spend much time in the unit, which is fair for the price point. Nothing about it is cozy -- it's more what we used to call an "efficiency."
There were just a couple of "knocks" on the unit. The bathroom and shower are very small. I'm 6'2" and 230 lbs and had to leave the bathroom door open to use the toilet and could only dry off after a shower by entering the studio area. For two days by myself, not a problem. But I wouldn't want to travel with a partner like that. (Again, not unreasonable for the price point but might not meet your needs.)
