My friend and I had our annual week trip and Sakura was just right where we needed it to be - not too far from main areas (transportation, markets, restaurants plus Ueno) but well located at a neighborhood area. The staff was very easy to communicate with and was very helpful from checking in to when we have questions to getting a taxi for us when we checked out.
The rooms and the shared areas are always cleaned. The room itself is straightforward - a clean bed, clean floor, a table and a working AC and a window - perfect for us who was gone most of the day.
I would just say that we only ate once at the free breakfast as it was only toast, soup and coffee/tea - you can buy your own full breakfast. My friend and I rarely got hungry in the morning so we skipped the rest of breakfast for the next 4 mornings.
I do would like to say, the bunk beds was surprisingly comfortable and I was on the top bunk so I slept good every single night.
Overall, I would stay there again if I ever come to Tokyo! A lowkey but international type of stay. Oh! Did I mention, the 24/7 access to in-house drinks and food was a huuuuge plus for downtime.
Thank you for having us Sakura
