Vn is a great host: open, direct and attentive. He knows what you need. I'm especially thankful that he allowed me to leave my suitcase in the apartment on my last day of stay until almost midnight.
The location of the apartment is perfect, very close to tube stations as well as Hyde Park, not to mention other conveniences like restaurants, supermarkets, etc.
Facilities in the apartment are a little old, but adequate. The shared bathroom (gentlemen's) is quite narrow, so it's not easy to move about when you take a shower. That's an inconvenience but wasn't too much trouble for me. Vn and Dipesh (a very nice young man who works for Vn) are both late risers, so I never had to wait to use the bathroom.
The bedroom is actually inside the kichen, though a separate room. It might be a concern for some people, but I didn't have a problem. There was no noticeable noise or smell. You get a desk (big enough for me) with shelves, which are very useful. Wi-Fi is really fast.
My advice to future guests is to bring your own body wash, shampoo and slippers, since they are not provided by default. I myself had no body wash, but Vn was kind enough to give me a new bar soap.
