Ruth's apartment was truly fantastic. I always appreciate very detailed reviews so I will try to include all of my observations for anyone that it may help.
I stayed for a month and the flat was very clean and spacious for one person (would be plenty for 2 as well!) and as a solo female, I felt very safe by the building security. There is a lift in the building which was very nice for bringing up luggage/groceries/when your legs are tired after a long day of walking! Since I was there for a month, Ruth even had the apartment cleaned for me halfway through my stay which was amazing.
I worked from home while I was here and the wifi was very reliable and allowed me to work with ease. The TV has cable as well as Netflix, YouTube, Google Play, and Amazon Video which was a nice bonus! There are several "desk" options if needed, although I usually opted for the very comfortable couch!
Kitchen is very well equipped. I will note that there is not a microwave but this was not an issue for me. The bed, pillows, and duvet were very comfortable. The terrace was a true game changer for me! An incredible view to wake up to every day and very spacious to enjoy drinks, dinner, or just to read a book in the afternoon. There was plenty of room to store my belongings - a large wardrobe, clothing rack, and hanging shelves with plenty of hangers provided.
The bathroom was very modern and fully stocked with anything you may need (body wash, hand soap, shampoo, conditioner, toilet paper). The water pressure was excellent and hot water was always quickly available. It was nice to have the tub in case you wanted to take a bath!
There is a washing machine and detergent was there for me upon arrival. Ruth has also provided a very large drying rack for your clothes.
You truly cannot beat the location. Paddington, Queensway, and Bayswater stations are all within a 10 minute walk and there is a bus stop 2 minutes down the street. You can really get anywhere in London with all of these options so close by! Additionally, there are a few great markets on the street for any small needs (drinks, groceries, snacks, toiletries, souvenirs) as well as a great breakfast cafe, Greek restaurant, pub, and hotel bar. In about 10 minutes you can get to larger supermarkets for bigger grocery runs if needed.
The neighborhood is quiet, beautiful, and well lit - I always felt very safe. It gave me the feeling of "living like a local" vs a more touristy area. (Although you can get to those spots quickly if you wanted to!)
Ruth was always on hand to answer any questions and responded very quickly. She even had fresh flowers waiting for me upon arrival!
The only negative I would add (just to be fair + balanced!) was the construction noise. The apartment below was being renovated during my stay and the noise was pretty loud + constant. However, this is of course not Ruth's fault and she even offered to come back to the flat and tell them to quiet down. Luckily, I did not have meetings so the noise wasn't a huge deal for me. If you're spending your days out and about in London, you wouldn't notice! They were always finished by or before 5pm.
I would highly recommend a stay here to anyone. If you want to make the most out of your trip to London, this is the place to stay! I hope to come back someday.
