This is a hotel where you'd want to be a regular guest.

Hotel stayed: Sotetsu Fresa Inn Kitahama

A bath that is filled with hot water made from the purified water that flows throughout the hotel, which has become the hotel's source of pride. For someone like me who is particular about water, this hotel is one of the few hotels that is obsessed about clean water. Bath salts are given for free at the front desk. Put the bath salts in the bath and then get in the water to relax. It will be good for getting rid of fatigue and boosting your spirit. While it is just my personal opinion, I think rather than getting in a sauna, this is better for your metabolism, and it will make your body better and healthier.
As usual, the members of the hotel's staff are accommodating and check-in and check-out is convenient. I will also use it.


It was a good hotel.

Hotel stayed: Sotetsu Fresa Inn Nagoya-Sakuradoriguchi

I stayed here for a week because of my work transfer.
・There are abundant amenities at the 1st floor lobby (aside from tea and bath salts, they also provide facial lotion and cotton)
・Water from water purifiers
 Less skin irritation than regular tap water


Hotel stayed: Sotetsu Grand Fresa Osaka-Namba

The water used in the guest room facilities is purified, so I was able to use the water with peace of mind. The good-quality water will make your stay more pleasant.


I recommend the bath.

Hotel stayed: Sotetsu Fresa Inn Kitahama

The bathroom does not have a large bath, but this hotel uses purified water, and it's nice that the water is gentle on the skin. In addition, the bath agent is free, so I was able to feel comfortable in the bath in the guest room, too. The staff responds quickly, and if this package and rate are available, then I would like to stay here again.


Hotel stayed: Sotetsu Fresa Inn Yokohama-Higashiguchi

I was quite impressed with the purified water. Even though "Tap Water" in all other hotels, but I did not drink the water straight from tap. I boiled had to boil the water and then cool it before I drank it. I was able to drink the water with peace of mind. Thank you very much.


A compact and clean room

Hotel stayed: Sotetsu Fresa Inn Osaka-Shinsaibashi

There is only a bed and a sofa for relaxation, but it felt so clean that I got to relax. In addition, the hotel apparently has its own water purification equipment, and it did not smell of water, so bathing was pleasant as well.


A hotel with good water

Hotel stayed: Sotetsu Fresa Inn Kitahama

I stayed at the hotel for the second time after I stayed there in September. This hotel is really a hotel with good water. Aside from the drinking water, the water used in the bath, toilet and all other areas in the hotel is purified, so I would recommend this hotel to those who are particular about water. This hotel does not have a large bath, but the bathtub in the guest room is also spacious, and there are many kinds of bath agents and shampoos available at the front desk, so I don't think you'd mind that they do not have a large bath. On the other hand, I like it because I can enjoy bath time in a leisurely manner.
