Overall the location was great, and the apartment was as the photos look. The beds are comfy enough though the mattresses are on the softer/thinner so if you’re heavier it may be a bit uncomfortable. Given the top level it was pretty quiet and the stairs are mostly carpeted which made them easier to go up/down on. But 4 flights is a lot so be warned! Good mobility required.
For 4 people it was good value and plenty of space for central London.
We had some serious miscommunication during check-in -- this residence requires the download and use of a third party app to access the outer door, and the host needs to approve you as a user before too — that wasn’t listed in the description before we chose it and only shared a few days ahead. While it was eventually sorted, I was dismayed at the 4+ hour response time on the checkin day. The host’s phone number is listed at the very bottom of one of the instruction sets JFYI but you can’t call her thru the app. After my experience I believe future checkins will be smoother for others but just a heads up!
