The stay at Carlos's was great. I would highly recommend his place due to the great value provided. Given the location (15 minute walk from Canary Wharf and 15 minute transit to central London), the space provided was perfect for a young professional getting settled in the city or a tourist looking for reasonably priced accommodation.
The house does have multiple occupants, anywhere from 5-7 other people depending on vacancy level of the downstairs Airbnb's. Their are 2 bathrooms on the second floor (and one on the first floor), which means that there is always a bathroom available and the kitchen is fairly large so there are no issues in terms of using that. As of writing this in late 2020, I found the other permanent occupants of house to great roommates and enjoyed the occasional movie night/dinner with them. I would note that the house is not perfectly silent, while everyone is considerate people do make noise (Particularly on Friday and Saturday nights) and you should expect a similar noise level to sleeping in a hostel with people walking up and downstairs, closing and opening doors, and chatting. I would note that when all the airbnb's are filled the internet can be a bit slow (To be fair this occurred during lockdown so it had 7 people all working or streaming videos at the same time), but I know that Carlos is in the process of getting a new provider with better speeds.
Carlos is a great host and responded quickly to my requests, going above and beyond by buying me a couple of extra amenities when I first moved (The type of extra I would not expect to be offered from an Airbnb). He also was always welcoming in terms of having drinks or providing recommendations on restaurants and activities.
