Ok, let me do an in-depth review...
First, I thought the apartment was just what we needed for a family vacation The flat itself is in an apartment building near Kilburn Station (Jubilee Line). It is maybe a two to three minute walk to the station at best when leaving the apartment building. You can go through the car park entrance on Exeter Road or through the front entrance on Shoot-Up Hill to access the building. It's best if you have luggage to go through the car park since you can take the middle elevator up to the flat. The front entrance has a flight of stairs once you go through the front door so be warned. As a separate note, Kilburn Station has a lift (elevator) to the tube platform so access is easy.
Neighborhood: Pleasant High Street with the usual local shops. There's a Tesco just past the station and a Sainsbury's a little further on so you have plenty of grocery opportunities. I didn't have any problems with the neighborhood itself whether during the day or when coming back from a concert late at night.
Getting around: Kilburn Station, as mentioned, is close to the apartment building and the Jubilee line takes you straight into Central London. If you prefer buses (or, in our case, they close Kilburn unexpectedly for the weekend lol) go out the front entry on Shoot-Up Hill Road, look to your right and just across the street and you'll see bus stop 'B.' The TFL GO app can give you more up to date information but from here you can ride a bus to the Baker Street tube station (Bakerloo line) or points beyond.
The apartment: With one exception it was very clean and had a nice atmosphere. You'll enter into a foyer where the living room and kitchen are to your right (separate rooms) and the bedrooms are to your left down a hall. The master bedroom has its own bath while the second hallway bedroom has a bath just across the hall. We had no issues staying in the master bedroom and my daughter enjoyed the other bedroom. The only real issue I had was with the hallway bathroom: the tub needed a good cleaning since it was a bit dirty. Minor issue though as the rest of the bathroom, as well as the master version, were clean.
The kitchen was small but modern and had a hob (stove), oven, microwave, washer/dryer (underneath the kitchen bar), dishwasher and refrigerator/freezer. The cabinets held a selection of everything from cups to cookware (basic but that's all you really need) to wine glasses. One of the other cabinets also had pacs for the dishwasher, detergent etc. which was very nice of the owners to provide. The appliances have master switches (each switch, such as the dishwasher, was labeled) above the kitchen counter to turn them on. The only downside to the kitchen was the kitchen door, entering onto a small kitchen, since it was an obstacle at times getting into the refrigerator.
The living room itself had a glass table with chairs on one end and a couch with TV on the other. I thought it was a nice place to entertain guests and I certainly had fun using my computer at the table while my wife and child watched TV. There were plenty of plugs throughout the apartment to use -- just bring your adapters. There are fans in each room which worked very well.
The host, meanwhile, was very responsive to questions and gave us a checklist pre and post stay that was simple to follow (how to pick up keys from the lockbox across the street, where the bin (trash) room was, etc.)
All in all, I thought the apartment was well worth the price paid given the location. The tube access was a real bonus considering I had a wife and daughter (especially beneficial after a long day of travelling!) I'd stay there again.
With that being said, there were a few 'cons' that I'd like to make others aware of. None of them detract from the apartment -- like I said, I'd rent it again -- but just so you're aware:
1. There are two locks on the front door -- a lower old-style key and a more modern key on top. If you unlock the bottom lock and then pull on the door knob while turning the top key to the right it will make it easier to turn the key. It was possible to turn the top key without doing so but I was a bit afraid I would break it off in the lock.
2. The Hoover washer/dryer literally needed its own instruction manual. Instead of labels (wash, dry etc.) there was a confusing array of symbols. Some of them related to the wash cycle (wash, delicate, yarn/wool, that sort of thing) while others could be sorted by guess or were a mystery. It took an internet search to puzzle it out and even then it was trial and error although we finally had a system going. Not that I complained; it was all part of the travel adventure lol.
3. There was a pool/exercise room on the listing. Apparently you have to book time to use it but can only use it if you're a resident. Didn't bother me since I got enough exercise just walking around London each day but just FYI.
Bottom line: Great apartment in a good location. You can't go wrong.
