Enough space in the room and on the balcony. The kitchen and bathroom are small but functional. Everything for self-catering. I forgot that there is no WiFi, but this is clearly stated in the description. We solved this by buying 4g traffic, and there were no problems - 4g network reception was excellent. Our stay at the apartments was great.
The only problem during stay was not the apartments, but the buses in Catania. We had constant problems - buses run extremely rare and often do not run on time. Usually we waited for the bus for about an hour, and sometimes even more! At the end we just walked to the center, it takes about 30 minutes and the road is not comfortable. We even had to walk with luggage to the center to take the bus to the airport. Not a single bus came on Saturday morning (before 10 am). My advice - use not only buses 935 and 948, but also 534 (5 minutes from the stop to the apartment on foot) and even BRT5 (15 minutes from the stop). May be even scooters :)
