Aya's place was amazing for us. We were two families, 4 adults, 4 kids. The 4 kids had their own sanctuary: a large bedroom with a loft. Two of our kids shared the loft up steps the other two were on floor level. They also had their own ensuite. The room opposite was also large with ensuite for two adults and the other two had a room downstairs which also had bathroom attached.
Beautiful sunken table in the living area which had seating for all 8. Heating in all rooms, this place was a true sanctuary.
Also, easy to get here from the airport on the Keisei Skyliner train. Go to Ueno Station then change to H17 Hibiya grey line to Iriya. Iriya station to Aya's house easy 10 min or less walk.
The train network in Japan so is amazing. We never waited more than a minute on any platform and all signage is so clear it is almost impossible to get it wrong.
After visiting busy areas like Shibuya and Shinjuku, about 30mins away on train, we were so happy to come home to a much quieter part of Tokyo. In saying that, still so much to see and do in this area. Sensoji Temple and opposite to it Nakamise shopping is amazing. Locals passing by on their bikes and watching school kids in their uniforms on way to school was lovely.
Ueno Park, just one train stop away had the best cherry blossom viewing for us (right time of year ofcourse). Also opposite Ueno station their is a huge interesting market.
Overall, don't think twice. I forgot to mention, showers, amazing. Many convenience stores for great in house meals.
