Buckle Street Studios is a great place to stay, especially if you're looking for a small slice of tranquility in the city center.
The location is great, in walking distance to not only one but two underground stations, as well as plenty of attractions and bus stops.
The micro studio was lovely; very quiet, clean, and soothing after the hustle of the city. The mini kitchen was great - I was not there long enough to really use it, but the option was really cool.
The hosts are very friendly and helpful, great people.
I would advise, as a solo female traveler, to keep your wits about you at night - but no more so than any other large city.
Genuinely loved it here, would stay again :)
