We had a great stay at the apartment. The location is excellent, very close to Euston train underground stations and close to Kings cross stations as well, very convenient access to every point in London and surrounding towns.
The apartment is very quiet at nights and days. It was excellent in terms of size for both our children and ourselves. Very well heated in every room and bathrooms.
The beds although have a very soft and thin mattress, at least to our taste. Also, it could be nice to have some hooks in the bathrooms for towels.
To summarize, we really enjoyed visiting London during Christmas and this apartment definitely contributed to our great experience. Frankie is a very communicative host. I can wholeheartedly recommend this apartment and the host.
