It's a good and clean place shared by two guest parties. A party consists of up to four people. We were two people and shared the house with a party of four but we never met them because we all were sightseeing or somewehere else. It's a big guest room for two people and still okay for four people. It was all clean and you don't have to worry about anything. You can't lock a door to your room but there are small lockers where you can lock your important things. Two stations and supermarkets are nearby. A lot of good restaurants can be found around the stations.
We have only seen Keita when we were checking-in. He's very nice and explains all you need to know about the place and your stay. You can always ask him anything and he'll provide you with information. Very recommendable!
