Cristina's place is perfectly located in a very quiet street but very close to everything. You can walk everywhere and it is very close to some lovely restaurants. We stayed in winter and it was very cold outside but the heating is brilliant and the flat gets very warm quickly.
The only small thing is that the hot water doesn't last long even when set to the right settings so it would not be able to cope with 4 people wanting a shower at the same time.
We had a lovely time and Cristina is very quick to respond to any messages.
