I stayed with my wife and daughter at Paul's rental in The Leonard Hotel & Apartments. It was a week-long trip from the US. The "executive summary" is this: I would not hesitate for a second to rent this apartment unit from Paul if we were to visit London again in the future. The trio combination of (1) the apartment (its layout/size, amenities, location, etc.), (2) its association with The Leonard Hotel, and (3) Paul being a great Airbnb owner is rare, in my opinion.
The rooms in the apartment are how they appear in the photos. But even after reading many prior positive reviews, I still was surprised by the spaciousness and high ceilings of the unit. Given that we were out sightseeing from early morning until late at night, we didn't spend a lot of time inside. But with an entry foyer, 2 bedrooms, 2 full bathrooms, a living room area with dining table, and a separate kitchen (with washer/dryer unit -- which we did use once), it was perfect for us. We stocked our fridge with water/drinks/snacks for the week (small market is only two blocks away), which worked well. Various normal wear and tear in terms of condition, but a few cosmetic imperfections here and there did not bother us in the least -- particularly in light of all the meaningful benefits/advantages the apartment offers. It's a first floor apartment, so there is some typical street noise to be expected -- but nothing that bothered us while sleeping or in any way had a negative impact on our stay. The street itself is a relatively quiet one tucked away off the main avenue(s).
The location was phenomenal. As stated in other reviews, it's probably a 2 minute walk to the Marble Arch tube station (off the northeast corner of Hyde Park) -- on the Central line. A good sampling of shops, pubs/restaurants right there on the quieter streets where The Leonard is located. It could not have worked better to get around to everything in the city. You easily can look at Google Maps and see how centrally located it is.
The apartment is attached to and associated with The Leonard Hotel (I suppose described as a classic "English-style" boutique hotel, with a lot of antiques & charm), which is an added bonus. We checked in at the hotel front desk and were able to store our luggage for several hours prior to our scheduled afternoon check-in time -- which allowed us to get a head start on a few hours of sightseeing. The hotel staff could not have been more pleasant or helpful the entire week. And they were kind enough to accept delivery on my behalf of football match tickets that were scheduled to arrive while we were out during the day. Essentially, you feel like a part of the hotel, but at the same time there is a sense of an independent apartment. It's a nice, unique mix.
Finally, Paul was a top-notch Airbnb owner. By chance, he was in the hotel lobby when we arrived, so we got to meet in person. Prior to our arrival and during our stay, he was incredibly promptly responsive to anything we inquired about. He even proactively reached out to me to let me know the football match tickets had arrived at the front desk, and also went out of his way to make dinner reservations for us one night when I asked about restaurants in the area. My family gives him five stars for our stay.
All in all, we could not have been more pleased with our rental. It absolutely was well worth it.
