This was my first time in London and so didn't really know what to expect. I was visited my son who was studying abroad. I arrived on Thursday and departed on Sunday. The room was just as advertised and served my purposes well. Nana's communication was very prompt, clear and helpful. I arrived early on Thursday and Nana accommodated me for an earlier arrival than was indicated in the listing. Grateful for that.
The location was very convenient via a short walk to the Baron's Court and West Kensington tube stops. I obtained an Oyster card for public transportation and was advised to purchase a pay-as-you-go card. I initially loaded it with 30 pounds and topped it off with about 7-10 more pounds. (Note that I travelled to Wimbledon three nights to see my son's theater production.) We rode a water taxi once for a short trip on Saturday that cost 6.50 pounds. Otherwise, 30 pounds would have been more than adequate to get back and forth to Heathrow and sight see the main attractions during my short stay.
The neighborhood is very quiet. I found that both pleasant and interesting, wondering a bit where all of the people were. Though there are plenty of cars parked on the street, I encountered only a limited number of people on the street. It's a short walk to the main roads where there are many options for coffee shops, convenience stores, pubs and other options.
The room itself was on the third floor and was very simple and straight forward ... sink, mini fridge, counter, tv and twin bed. I never used the tv. The wifi worked very well. I rarely encountered others within the building itself. I spent most of my time out and about and generally just used the room for sleeping and a short break in the afternoons. The only minor surprise was that the key to the room was a simple church key style. That felt a bit less secure to me but all was well in the end in that regard.
All in all, I would recommend the room for someone on a short stay, on a budget and simply looking for a place to sleep. And I would highly recommend working with Nana and her staff given her communication, accommodation for an early arrival and the consistency of the room to what was advertised.
