Overall a very positive review - we really enjoyed basing our London vacation from Alex' place.
The place appears to be used exclusively as an Airbnb property - so all the storage is available for use - no working around the owners things and trying to find some space to store your items. LOTS of storage available so you can definitely empty your suitcases and move in.
The one item to be aware of with this property is a set of steep and shallow stairs. Not an issue for most people, but if stairs give you problems you should factor this into your decision. While this wasn't a negative for me it could be for some. The good news is this is the only negative I have to report ;)
Coming from the US it was nice to find a 110V outlet in the bathroom for my shaver and my wife's flat iron (hair). Two bathrooms was very nice, one as an ensuite to the primary bedroom, which has a tub-shower combo. The second bathroom had just a shower.
The primary bedroom did have air conditioning. During our visit the outside temps got no higher than the mid 80s so we didn't miss having AC in the rest of the property.
Full kitchen and US sized refrigerator. I had enough pots, pans and utensils for cooking, although we did mostly eat out. Great pub 2 minutes walk toward Paddington if you truly detest cooking on vacation.
The beds were comfortable and the location was quiet in the evenings (can't comment on the days we were out and about). The general area was very clean and well kept. Some other reviewers have mentioned some exterior building maintenance so there is some scaffolding out front but the work didn't impact us at all.
In terms of location I was very pleased. We did likely all the typical tourist stuff around London and had no issues getting around. The property is exceptionally close to Paddington station so two fast rail options directly from/to Heathrow airport. Paddington also has an underground station. We mostly used the busses to get around and never had to walk more than 4 minutes to catch the right bus for our activity.
We did rent a car a couple days for some more remote journeys. I was missing the proper "resident" parking permit on the rental but had no issue parking directly in front of the property and was lucky enough to escape any ticket. With a little longer walk I likely could have found truly legal parking - but if you plan to stay in London no vehicle will be needed.
In addition to being close to Paddington there is also a nearby Waitrose grocery which has a very American grocery store feel within easy walking distance.
We arrived early on the same day as a previous check out, so while we couldn't officially check in until 3:00pm we were able to drop our bags, pick up the keys and head out for a little sight-seeing and grocery shopping while the property was being made ready for us. Upon our return it was ready for us to move in - all the sheets and towels freshly laundered and everything fabulously clean.
I didn't work while there, but the wifi had good strength and we did bring a Roku to stream and had no issues with the available speeds.
Overall the whole family was happy with the property and we'd be very happy to stay here again if we return to London.
