The hikes range from very easy to difficult. Many people say they find Cinque Terre has turned very touristy, and yes, we did see quite a few tourists. This in no way affected our stay however and we had an amazing time. We did stay in Manarola, which may have less tourists than Vernazza. It's wonderful but the church bell next door drove me crazy ringing all night on the half hour.
Some rooms have terraces, all have private bathrooms.
Shared bathrooms on floor. No double rooms. All rooms with private bathrooms.
