In the big picture, I would definitely stay here again. Charity was very quick to respond to questions. There was a delay in moving into this location, but the owners put us up for one night at another of their locations nearby.
The house was clean. The beds were comfortable. Upstairs there are 3 bedrooms with a total of five beds. Downstairs there's one bedroom with one bed. Having three toilets was convenient. The shower had hot water and very good pressure.
The kitchen had all the things we needed to cook some meals at home. Having the washer with the dryer was great. We also used the provided drying rack. After figuring out how the UK TV service works, we were able to watch the news and weather every morning.
Bexleyheath is a great little town. We felt safe where we were. There were no loud neighbors. You could walk to almost any amenity that you needed. There is a co-op and a Sainsbury Local right in town, with a larger Sainsbury just a short drive down the street. Bakeries, butcher shop and cafes all within walking distance.
The above ground rail is about a 5-minute walk. You can be downtown London in about 30 minutes. Get an Oyster Card and enjoy what London has to offer.
