A very nice little clean hotel near the metro station "Invalidovna". 3 stops (12 min.) - and you are in the very center of Prague! Those who wish can also walk (about 40 min. by tram lines). By the way, although the rooms are weak, Wi-Fi is available, you do not need to sit in the lobby. I can't say anything about the cost of living, the organization paid for it.
Good location, metro and tram service are close. There are 3 metro stops to the center, 15 minutes, and 20-25 minutes by tram. It can be reached on foot in 45 minutes.
The breakfasts at the hotel are good, especially when I have already been to other Prague hotels))) The staff is friendly. A refrigerator is needed in the rooms of the 3* building. And one room card is not enough for two people.
