The space is clean and cozy, just nice for three people, I personally think it would be too small for four people. The mattress is too soft with not much support, I got backache from it (some people like soft mattress so I think that’s just personal preference). The location is superb, just few minutes walk from subway station and plenty of bus stops around. The toilet is quite small as well. Noise cancellation is bad, on some nights at 2-3am we were woken up by people talking on the street, also when the neighbours come home late at night.
