The host Ludovica is very friendly, flexible and helpful.
Flexibility: You can check-in and out when you like, and Ludovica both wait for your arrival at they apartment the first day and come when you leave. We came late afternoon and she was ready for us and two days before we left we mentioned we would like to leave 09 o'clock in the morning and she was there on time :)
Helpful: 1) On our arrival she made a good introduction to the area and have various turistinfo ready. 2) She told us that we could always call/write if we had any questions, 3) We needed to print our flight ticket and she did that for us and we received them at check-out.
We can much recommend to stay here. It is a simple and functional apartment to a very fair price, located fine with metro/train 2 minutes walk away, 10-15 minutes walk from old town.
