First off, the place is extremely convenient to public transportation. 1 minute walk to the busses with only a 5 minute ride to 2 different tube stations and only 10 minutes into London.
The accommodations are simple, no frills and basic. Abrasive towels, simple bedding, and functional (but cheap) furniture throughout. No issues with hot water and having a washer (no dryer) was great. All that being said, if your looking for a simple place for your larger group to drop your bags and lay your head at night, Praveen's is great. If you are expecting nicer accommodations, maybe look elsewhere for now.
Praveen himself is a great host. He's communicates throughout your trip and is an absolute pleasure to deal with. If he were to upgrade just a few things at some point, this place would be an amazing AirBnB for all.
