Apartment was comfortable and clean. We had everything we needed. The terrace is cool, but the apartment is in the middle of crowded city so it's a little bit noisy (the whole area of Valetta and nearby cities are the same). The only minus of the flat is the lift - we got stuck in it for 20 minutes in the first day. Man who saved us told us that it is happening all the time.
Ana responds quickly and she let us check in and check out at any time, because there was no other guest after us. Thank you Ana!
