Good bits: Excellent communication with the hosts - very helpful and responsive. Easy check in. Clean. Comfortable bed. Cozy. Location is good - very close to beautiful Regents park and Euston. Adequate cooking/kitchen supplies. Appliances all worked.
Bad bits: The place is adequate... but is of a lower quality than the photos would have you believe. It is in an old building that and I think is partly, or previously (?), public housing - but - despite this, feels safe. There are additional furniture items like a single bed and added couch which make the place feel cluttered. I would call it a studio not a one bedroom apartment. It needs an overall spruce up and there are some broken things that need to be fixed.
Overall it was adequate for what I needed, but wouldn't rave about it and I don't think I would stay again.
