The apartment - everything was perfect, just as described and more. There is a practically a separate entrance to this section, the bedroom is large and bright, bathroom is comfortable, separate room for the hair dryer, etc.
The location - perfect if you need to go to IFAS (4 minute walk). On the same street there are lots of cafes, supermarket, pizza place, Chinese restaurant, dry cleaning, ATM, etc. Very safe. 25 minute walk to Laurentina metro, but Valentina offers a ride if she's free. Bus stop right outside, but I did not use it. Very secure, gated entrance.
Valentina as a host is remarkable, the best I have ever met. She texted me every day to offer help, advice and inquire whether I needed anything. She speaks excellent English and loves to drive. Her little dog Totti is very friendly and never barks!
I stayed here for 11 nights, and have already booked my next trip for another 10 nights. No regrets at all!
