The apartment was perfect!
Nena told us the way to get to the apartment and when we arrive she was there waiting for us (there was a delay in the border with our bus). Nena leave us some maps of the city and told us some zones to go out for dinner/party. Also there were two welcome chocolates :) she was very kind.
The apartment is as shown on the pictures and the wifi was great. It is cozy and has all the necesary things, besides it has a small patio.
The apartment is well comunicated and you can arrive to the center just taking the tram.
We were in three apartments in our tour and this one was the BEST.
To summarize: cozy apartment, warm and well comunicated.
