Ursula's place is at the heart of city and very convenient to get to the tourist attractions. Very close to metro and good cafes as well. There were few hiccups though- we booked the room shown in photo 4 weeks ago but just 5 days before we were supposed to arrive, she asked us if we can stay in windowless room as the other room was booked. The window less room was really tiny and was not comfortable. It sort of left sour taste.
Also the building does not have lift and her apartment is on second floor, so if you have heavy luggage, you might wanna consider it.
