I had a great time at Ana's apartment. It is very well located, you can walk to many places and the metro and train station are just minutes away; also the tram 28 is just right there. The apartments is really comfortable, bright and with everything I needed. Also it is in a very quiet place. I was traveling alone and felt safe all the time. Ana was very responsive to my emails, she always responded within minutes! and she even booked a taxi for me as I was leaving really early in the morning.
I recommend Ana's apartment!
Thanks Ana!
