I spent 8 nights at Nica’s place. I found it generally as described. There were advantages and disadvantages but on the whole it was a positive experience for me. The main advantage from my perspective is that it is outside of the main tourist strip but very well served nonetheless by public transport... trains, streetcars and buses are all within a 5 min walk and in a 10- 20 minutes you can reach any of the main historic attractions in the city. It is also a safe area even getting back late at night.
One of the disadvantages is the noise from the busy street. I was very worried the first night as there were frequent ambulance and police sirens, but the following nights were quieter and the double glazing muffled the regular street traffic to just a white noise. So although I’m a poor sleeper I actually slept well.
The bed is comfortable but furnishings and equipment are spartan especially in the kitchen. Also, the shower cabin is very small so not appropriate for XXL sizes.
I didn’t meet Nica. Her son checked me in and communications with both were easy and efficient. I recommend to people who plan to be out all the time and just need a place like a hotel room than those who would prefer a 'homelike' place where you can cook and relax.
