Keiko's place is in a great location - a few metres from Minowa subway station and walking distance from Asakusa (20 mins), Ueno (30 mins) and Yanaka (30 mins). If you fancy a change from Japanese food, there's an excellent Mexican restaurant close by called Sol Tokyo.
The flat is spacious with everything you need for a comfortable stay. Keiko is very kind and she had prepared face masks, snacks and fruit for our arrival. If you need help with anything, she is very quick to reply.
The only thing to consider is that this flat is on a main road which can be noisy at night. We moved the futons and slept in the living area which was much quieter.
Highly recommend!
