Christina's place is just great, super clean, all new, well equipped, good wi-fi, very comfortable bed, and in a very quiet neighborhood, so you can rest well. Easy access by train from the airport, and not too far from the city center either by bus or train, a 10 minute walk to the beach promenade, and 3 minutes from 2 large supermarkets. Also the coded lock at the door makes it very easy to get in, no picking up keys required, and very safe.
And Christina herself is very nice and accommodative, so staying at her place is an overall very good experience, and great value for the money.
Only challenge would be if you have a lot of luggage, or very heavy, as it is a 3rd floor by stairs, but other than that all is perfect.
